Abstract:

In this paper we report the preparation of two (h3-allyl)carbonylnitrosyltriphenylphosphine iron complexes i.e.(p-allyl)carbonylnitrosyltriphenylphosphine iron (1) and (2-methyl-p-allyl) carbonylnit rosyltriphenylphosphine iron (2). These complexes (1) and (2) were prepared by reacting (p-allyl)dicarbonylnitrosyl iron and (2-methyl-p-allyl)dicarbonylnitrosyl iron with triphenylphosphine under inert atmospheric conditions. Both the resulting complexes were sufficiently and well characterized by IR, 1H NMR, 13C NMR, ESI/MS, HRMS and single crystal XRD. Triphenylphosphine ligand was found to be strong sigma donor and replaced carbonyl ligand readily. XRD revealed that the geometry of iron in both complexes is distorted octahedral.

Full text

Abstract:

Different alkyl/aryl 7-hydroxy-8-coumarinyl ketones were converted to 7-O-allyl and 7-O-cyclohexenyl ethers and the study of hitherto unreported sigmatropic rearrangement on 7-O-allyl and 7-O-cyclohex-2'-ene-1'-ylcoumarinyl ketones prepared is accounted herein. The rearrangement yielded alkyl/aryl 6-allyl-7-hydroxy-8-coumarinyl ketones 3 and alkyl/aryl 6-cyclohex-2'-en-1'-yl-7-hydroxy-8-coumarinyl ketones 7 as the major products. Interestingly, unusual selectivity was observed in the case of alkyl 7-O-allylcoumarinyl ketones. Thus alkyl 3-allyl-7-hydroxy-8-coumarinyl ketones 4 and alkyl 8-allyl-7-hydroxy-6-coumarinyl ketones 5 were the outcome from alkyl 7-O-allyl-8-coumarinyl ketones and alkyl 4-methyl-7-O-allyl-8-coumarinyl ketones, respectively, albeit in minor yields.Key words: allyloxycoumarinyl ketones, 7-O-cyclohex-2'-en-1'-ylcoumarinyl ketones, sigmatropic rearrangement, 3-allylcoumarinyl ketones, 8-allylcoumarinyl ketones.

Abstract:

Five new platinum(II) complexes bearing a eugenol and a quinoline derivative, namely [η2-4-allyl-2-methoxy-1-(propoxycarbonylmethoxy)benzene]-trans-dichlorido(quinoline-κN)platinum(II), [PtCl2(C15H20O4)(C9H7N)], (2), {η2-4-allyl-2-methoxy-1-[(propan-2-yloxy)carbonylmethoxy]benzene}-trans-dichlorido(quinoline-κN)platinum(II), [PtCl2(C15H19O4)(C9H7N)], (3), [η2-4-allyl-2-methoxy-1-(propoxycarbonylmethoxy)benzene]chlorido(quinolin-8-olato-κ2 N,O)platinum(II), [Pt(C9H6NO)Cl(C15H20O4)], (4), {η2-4-allyl-2-methoxy-1-[(propan-2-yloxy)carbonylmethoxy]benzene}chlorido(quinolin-8-olato-κ2 N,O)platinum(II), [Pt(C9H6NO)Cl(C15H20O4)], (5), and [η2-4-allyl-2-methoxy-1-(propoxycarbonylmethoxy)benzene]chlorido(quinolin-2-carboxylato-κ2 N,O)platinum(II), [Pt(C10H6NO2)Cl(C15H20O4)], (6), have been synthesized and fully characterized spectroscopically. A single-crystal X-ray diffraction study was carried out for complexes (2) and (4)–(6). PrEug [or 4-allyl-2-methoxy-1-(propoxycarbonylmethoxy)benzene] in (2), (4) and (6), and iPrEug (the propan-2-yloxy analogue of PrEug) in (3) and (5) coordinate with PtII at the ethylenic double bond of the allyl group. In (2)–(6), the donor N atom of the amine group occupies a trans position with respect to the double bond. A comparison of the IC50 values of 0.38–29.23 µM for (2)–(6) with cisplatin, as well as other platinum(II) complexes, indicates an excellent in vitro cytotoxicity against the KB, LU, Hep-G2 and MCF-7 cancer cell lines, with the highest cytotoxic effect (IC50 = 0.38–1.99 µM) being for complexes (4) and (5) bearing a quinolin-8-olate ligand.

Abstract:

The aim of this preliminary research was to synthesize derivatives of eugenol such as 4-allyl-2-methoxy-6-nitrophenol (2) and 4-allyl-2-methoxy-6-aminophenol (3). The result could be used as a reference on the transformation of eugenol to its derivatives. Theoriticaly nitration of eugenol (1) by nitric acid could produced 4-allyl-2-methoxy-6-nitrophenol (2) and followed by reduction could achieved 4-allyl-2-mehtoxy-6-aminophenol (3). The formation of this product was analyzed by analytical thin layer chromatography (TLC) and GC-MS. These analysis showed the formation of product (2) and (3) were visible. TLC showed product (1) less polar than eugenol and gave orange colour, and supported by GC-MS which showed molecular ion at m/z 209 due to the presence of -NO2 by replacing one H at 6 position of eugenol. Product (3) was afforded by reduction of (2) with Sn/HCl and tlc analysis showed compound (3) more polar than eugenol (1) and (2) and supported by GC-MS which showed molecular ion at m/z 179 due to the presence of -NH2. Keywords: Synthesis, 4-allyl-2-methoxy-6-aminophenol, Eugenol

Abstract:

Pd-Et3B catalytic system promotes the generation of allyl cations, allyl anions, and zwitterionic trimethylenemethane species from the corresponding allylic alcohols. Allyl cations react with a wide variety of nucleophiles, e.g., amines, active methylene compounds, 1,3,5-trihydroxybenzene, indoles, aldehydes (at the α-position). The reaction is extended to dehydrative Grob fragmentation of 1,3-diols. Allyl anions react with aldimines to give homoallyl amines. Zwitterionic trimethylenemethane, generated from 2-methylene-1,3-propanediol, reacts with aldehydes and aldimines to provide 3-methylenecyclopentanols and 3-methylenepyrrolidines, respectively. Vinyl epoxide can be utilized as a synthetic equivalent of 3-butenyl 2-anion-1-cation.

Abstract:

Abstract The reaction of dimeric π-allyl palladium chloride with 1-azadienes 1 ( R -N = CH-CH = CH-R') affords the mononuclear complexes (π-Allyl)Pd(L)Cl 2. Two independent intramolecular rotational motions are detected by NMR methods. These complexes (with R ' = Aryl) react with silver tetrafluoroborate, preferentially in the presence of 1, to the cationic complexes [(π-Allyl)Pd(L)2]+ BF4-, 3, which are also non-rigid with respect to ligand rotation on the NMR time scale. Complexes 3 catalyse the 2 :1-cyclo-cooligomerization of butadiene and 1-azadienes. This reaction to compounds 4 constitutes the first example of a very regio- and stereoselective formation of cyclohexanes from three C = C double bonds. The structure, substitution pattern and conformation of 4 are assigned on the basis of 2D -correlation NMR spectroscopy.

Abstract:

The unsymmetrically substituted imidazolium salt 1-ethyl-3-allyl-imidazolium bromide 1 was synthesized by treatment of imidazole with one equivalent each of n-butyl lithium and ethyl bromide followed by treatment with one equivalent of allyl bromide. The symmetrically substituted derivatives 1,3-diallyl-imidazolium bromide 2 and 1,3-bis(3-methyl-2-butenyl)-imidazolium bromide 3 were obtained from imidazole and two equivalents of allyl bromide or 4-bromo-2-methyl-2-butenyl bromide, respectively, in the presence of sodium hydrogencarbonate as a base. The imidazolium bromides 1- 3 react with Pd(OAc)2 to afford the palladium(II) dicarbene complexes trans-[PdBr2(L)2] (L = 1- ethyl-3-allyl-imidazolin-2-ylidene, 4; L = 1,3-diallyl-imidazolin-2-ylidene, 5; L = 1,3-di(3-methyl-2- butenyl)imidazolin-2-ylidene, 6) by in situ deprotonation of the imidazolium salts. The X-ray structure analyses of 4- 6 show all three complexes to be mononuclear with palladium(II) coordinated in a square-planar fashion by two carbene and two bromo ligands.

Abstract:

The electrochemical reduction of 1-bromo-2-butene and 1-chloro-2-butene in DMF at a Hg electrode has been studied by polarography, cyclic voltammetry (CV), a rotating ring-disc electrode and controlled-potential coulometry. A CV study using a gold electrode has also been carried out for these compounds to identify the detected intermediates. Two consecutive one-electron reduction processes are found for 1-bromo-2-butene in polarography and in CV using Hg electrode. The first process is initiated by the irreversible one-electron cleavage of the carbon-bromo bond to give the allyl radical and Br-, which is the rate-determining step. The second one follows a first-order EC mechanism, being initiated by generation of the allylmercury anion via a one-electron reduction of the allylmercury radical, previously formed by reaction of the allyl radical with Hg. A single irreversible two-electron process is found for 1-chloro-2-butene under all voltammetric conditions and for both compounds in CV using a gold electrode. Additional anodic peaks detected in CV, as well as anodic waves found at the rotating Hg ring electrode, are ascribed to oxidation of the allylmercury anion and the allyl anion.

Abstract:

The structures of new extractives from the tubers and aerial parts of Eupomatia bennettii F. Muell. have been assigned as follows: eupomatenoid-15, 2-(4′-methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (1); eupomatenoid-16, 7-methoxy-2-(4′-methoxyphenyl)-3-methyl-5-(E)- propenylbenzofuran (3); eupomatenoid-17, 5-allyl-7-methoxy-2-(4′- methoxyphenyl)-3-methylbenzofuran (5); eupomatenoid-18, 5-allyl-2- (3′,4′-dimethoxyphenyl)-7-methoxy-3-methylbenzofuran (6). Eupobennettin was shown to be (2′α,3′α,4̸β,5′α)-5-[3′,4′-dimethyl-5′-(3′,4′,5′-trimethoxyphenyl)tetrahydrofuran-2′-yl]-2,3-dimethoxyphenol (7). Spectroscopic studies and a biomimetic synthesis proved that bennettinone was 2-(4′-allyl-2′-methoxyphenoxy)-1-(3′,4′-dimethoxyphenyl)propan-1-one (10).

Abstract:

The reactions of [M2Cl2(μ-Cl)2(PR3)2] with acetamidines in 1:2 stoichiometry afforded mononuclear complexes, [MCl2{ArNHC(Me)NAr}(PR3)] (I) (M = Pd or Pt; R3 = Et3, Bu3, Me2Ph, MePh2; Ar = Ph or 4-MeC6H4 (tol)). Treatment of [M2Cl4(PR3)2] with Li[ArNC(Me)NAr] under anerobic conditions gave acetamidino-bridged binuclear complexes, [M2Cl2(μ-ArNC(Me)NAr)2(PR3)2] (II). The reaction of [Pd2(μ-Cl)2(η3-allyl)2] with Ag[ArNC(Me)NAr] gave acetamidino-bridged allyl complexes [Pd2(μ-ArNC(Me)NAr)2(η3-allyl)2] (III). All the complexes were characterized by elemental analyses and NMR (1H, 31P, 195Pt) spectroscopy. The mononuclear complexes (I) exist in two isomeric forms differing in the coordination of monodentate acetamidine ligand. The 31P and 195Pt NMR data on binuclear complexes (II) indicate that there is no significant Pt–Pt interaction. The allyl complexes (III) (allyl = C3H5) exhibit formation of all three possible isomers, whereas methallyl (allyl = C4H7) derivatives exist only in one configuration. Key words: palladium, platinum, acetamidine, NMR (1H, 31P, 195Pt), mononuclear complexes, binuclear complexes.

Abstract:

Allyl esters, frequently used in the fragrance industry, often contain a certain percentage of free allyl alcohol. Allyl alcohol is known to have a potential for delayed skin irritation. Also present in the finished product are different solvent systems, or vehicles, which are used to deliver the fragrances based upon their intended application. This study was conducted to determine whether different vehicles affect the skin irritation potential of five different allyl esters. The allyl esters tested were allyl amyl glycolate, allyl caproate, allyl (cyclohexyloxy)acetate, allyl cyclohexylpropionate, and allyl phenoxyacetate in the vehicles diethyl phthalate, 3:1 diethyl phthalate:ethanol, and 1:3 diethyl phthalate:ethanol at concentrations of 0.1%, 0.5%, 1.0%, and 2.0% ( w/w). A modified cumulative irritation test was conducted in 129 human subjects. Test materials (0.3 ml) were applied under occlusion to skin sites on the back for 1 day (24 h) using Hill Top chambers. Irritation was assessed at 1, 2, 4, and 5 days following application of test materials. Cumulative irritation scores varied considerably among test materials. There were no delayed irritation observations. The highest irritation scores were observed at the 2.0% concentration for all test materials. The irritation scores for allyl amyl glycolate, allyl (cyclohexyloxy)acetate, and allyl phenoxyacetate were highest in 1:3 diethyl phthalate:ethanol, thus the resulting calculated no-observed-effect levels, 0.12%, 0.03%, and 0%, respectively, were much lower for this vehicle compared to the diethyl phthalate vehicle, 0.33%, 0.26%, 0.25%, respectively. These data showed a trend for lower concentration thresholds to induce irritation when higher levels of ethanol were used in the vehicle.

Abstract:

Chemical transformations of 13 diverse allyl(alkyl)-aryl ethers, easily prepared using Williamson reaction of different hydroxyarenes and allyl bromide and alkyl (n-butyl, n-octyl) bromides, were studied. Thermal aromatic Claisen rearrangement of allyl-aryl ethers to obtain ortho-allyl phenols (naphthols) employing propylene carbonate as a nontoxic and biodegradable solvent was described for the first time. The use of this green solvent allowed to enhance notably product yields and reduce significantly the reaction time comparing with the use of 1,2-dichlorobenzene, toxic solvent, which is traditionally employed in this type of Claisen rearrangement. Three-component Strecker reaction of selected alkyl(allyl)-aryl ethers with formyl function on aryl fragment, piperidine and potassium cyanide in the presence of sulfuric acid supported on silica gel (SSA, SiO2-O-SO3H) under mild reaction conditions was used in the preparation of new γ-amino nitriles, analogues of alkaloid girgensohnine [2-(4-hydroxyphenyl)-2-(piperidin-1-yl)acetonitrile], a perspective biological model in the search for new insecticidal agrochemicals against Aedes aegypti. The use of SSA, an inexpensive and reusable solid catalyst, allowed to obtain new series of 2-[4-alkyl(allyl)oxyphenyl]-2-(piperidin-1-yl)acetonitriles in short time at room temperature with good yields.

Thioglycoside 5 in the presence of methyl triflate and glycosylbromide 6 in the presence of silver triflate were used as glycosyl donors for condensation with benzyl 2-acetamido-3-O-allyl-6-O-benzyl-2-deoxy-α-D-glucopyranoside (7), to give benzyl 2-acetamido-3-O-allyl-6-O-benzyl-4-O-(3,4,6-tri-O-benzyl-2-deoxy-2-phthalimido-β-D-glucopyranosyl)-2-deoxy-α-D-glucopyranoside (8).

Abstract:

The exo/endo[4+2]-cycloadducts of Cl2Si=CHCH2tBu and cyclopentadiene 1 are transformed into the Si-dimethoxy- and chloro-methyl-substituted derivatives 2 and 4. In the case of the 2-silabicyclo[2.2.1] compounds 2 (R1 = R2 = OCH3), 3 (R1 = R2 = CH3) and 4 (R1 = Cl; R2 = CH3) the allyl cleavage with HCl/ether gives the ring opened products 8, 9, and 10 in good yields. The reaction can also be carried out with HBr/ether. In 1 the cleavage of the allyl-silicon bond is disfavoured due to the two chlorine atoms at silicon. Instead HCl adds to the C=C double bond and stereospecifically gives the exo-6-chloro-2,2-dichloro-3-exo/endo-neopentyl-2-silabicyclo[2.2.1]heptanes 5. When the stronger acid CF3SO3H is used no addition to the double bond is observed but only the allyl cleavage takes place to give the triflate 7. The ring opened cyclopentene compounds can be reduced by LiAlH4 to give the corresponding Si-H-compounds 19 and 20. Intramolecular hydrosilylation of 19 leads to the exo/endo-2,2-dimethyl-3-neopentyl-2-silabicyclo[2.2.1]heptanes 21 and so the former bicyclic structure is regenerated.

Abstract:

So far, few microclusters containing vanadium have been described in the literature. In this report, the synthesis protocol for the preparation of oxovanadium (IV) microclusters with 2-phenylpyridine is shown for the first time. Moreover, the crystal structure of these microclusters is also studied through the use of X-rays. The morphology of the prepared crystals is investigated using a field-emission Scanning Electron Microscope (SEM). The new compound, after activation by modified methylaluminoxane as the catalytic system, is investigated regarding the oligomerizations of 3-buten-1-ol, 2-chloro-2-propen-1-ol, allyl alcohol, and 2,3-dibromo-2-propen-1-ol. The products of oligomerization are tested by the TG-FTIR and MALDI-TOF-MS methods. Moreover, the values of catalytic activities for the new oxovanadium(IV) microclusters with 2-phenylpyridine are determined for the 3-buten-1-ol, 2-chloro-2-propen-1-ol, allyl alcohol, and 2,3-dibromo-2-propen-1-ol oligomerizations. Oxovanadium(IV) microclusters with 2-phenylpyridine are shown to be very highly active precatalysts for the oligomerization of allyl alcohol, 2,3-dibromo-2-propen-1-ol, and 3-buten-1-ol. However, in the case of 2-chloro-2-propen-1-ol oligomerization, the new microclusters are seen as highly active precatalysts.

The effect of a various reaction conditions (i.e. the concentration of [Ru] complex, the reaction temperature, reaction gas atmosphere) together with trace amounts of allyl hydroperoxides formed via autoxidation reaction of allyl substrates on the productivity of catalyst was examined in detail. Moreover, the significant role of the allyl substrate structures on the catalytic activity of ruthenium catalysts were also recognized. The optimal parameters of the scaled-up synthesis together with productivity of catalyst were first established.
