Повний текст джерелаThe concept of metal-ligand bifunctionality was successfully applied for an enantioselective aza-Michael reaction by employing well-defined ruthenium amido complexes. The catalyst was optimised and the corresponding chiral indoline β-amino acid derivatives were obtained with high enantioselectivities. Next, a straightforward enantioselective bifunctional organocatalytic approach was also developed. Employing hydroquinidine as catalyst the corresponding cyclic products were obtained in excellent enantioselectivities and quantitative yields. These compounds can be selectively deprotected and applied to peptide synthesis.

Abstract This thesis involves the synthesis, characterization of a new class of aza-based bidentate phosphinic amide ligands, the study of catalytic applicability of the phosphinic amido palladium complexes to various Heck-type C-C formation reactions, and the kinetic and theoratic study of organotungsten Lweis acid catalyzed Diels-Alder reactions. The thesis also includes discussions of a new path for P-C cleavage which is induced by the basicity of the reaction system. The results and discussion will be categorized into four independent chapters. In the first chapter, we mainly focused our research efforts on the syntheses, structural characterization of a series of gold nanosurface-immobilized palladium(II) complex catalysts, and their catalytic reactivity towards various Heck-type C-C coupling reactions. Spherical gold nanoparticles of a diameter of 2.7 ± 0.5 nm in size were used as support for molecular palladium complex catalysts. These gold nanoparticles were obtained by the chemical reduction method using NaBH4 as the reducing agent to reduce HAuCl4・3H2O in the presence of CH3(CH2)7SH stabilizer. The compound [HS(CH2)11N(H)(O)P(2-py)2] (4), which was derived from Br(CH2)11OH, with both ends having coordination capability was specially designed as the linker between molecular metal catalysts and metal nanosurfaces. The thiol end (HS) of the anchoring linker can be put onto gold nanoparticles’ surfaces by ligand exchange at elevated temperature. Four types of “soluble” or “dispersible” gold nanoparticle-supported ligands, Au−L-A~D (Au−L = Au−S(CH2)11N(H)P(O)(2-py)2), anchored with different amounts of spacing linkers with diameters of 3-5 nm in size were synthesized by design. Again, these gold nanoparticle-supported ligands can be dispersed (or dissolved) in various organic solvents, such as CH3Cl, DMSO, MeOH, EtOH and CH3CN, etc. The direct reaction of the above-mentioned four types of ligands, Au−L-A~D, with palladium (II) complex, Pd(CH3CN)2Cl2, resulted in the formation of “soluble” gold nanosurface-immobilized palladium complexes, Au−L−Pd-A~D (Au−L−Pd = Au−S(CH2)11N(H)P(O)(2-py)2PdCl2). The diameters of the gold cores remain unchanged after palladation, and these gold nanoparticles dissolve in DMSO and MeOH fairly easily. Taking the advantage of the high solubility, A rapid and precise method to structurally characterize these systems (Au−L−Pd-A~D) using solution 1H, 13C and 31P probe NMR spectroscopy becomes accessible. In addition to the NMR technique, the atomic absorption spectroscopy (AA) was also used to determine the amount of Pd catalysts anchored on gold nanoparticle’s surface. By performing a size-and-particle calculation based on the TEM image, one can obtain the average number of Pd catalysts and stabilizers on each gold nanoparticle’s surface. These gold nanoparticle-supported palladium complexes, Au−L−Pd-A~D, were demonstrated to be highly effective catalysts for various Heck C-C coupling reactions. The turnnover frequencies (TOF) of 35000-45000 h-1 were obtained for the A-D systems. The controlled experiment of the molecular palladium complex catalyst HO(CH2)11N(H)(O)P(2-py)2PdCl2) (6) promoted Heck reactions gave TOF values of 10,000-17,000 h-1, which are 3~4 times less than those obtained for the Au−L−Pd-A~D catalytic systems. The kinetic studies revealed that a second order kinetic behavior was found for all the homogeneous 6-catalyzed Heck C-C coupling reactions. However, the kinetic studies showed that the gold nanoparticle-supported catalytic systems deviated dramatically from a normal second order kinetic behavior. In the second chapter, A new class of bidentate, aza-based phosphinic amide ligands, RNHP(O)(2-py)2, where R = CH2CH(CH2)9, HOCH2(CH2)10, (O)3Si(CH2)11, was efficiently synthesized via a one-pot Staudinger reaction of organic azides and 2-pyridylphosphines followed by in situ hydrolyses. The complex CH2CH(CH2)9NHP(O)(2-py)2 was structurally characterized, and its ORTEP drawing showed a pentavalent, trigonal pyramidal arrangement around the P center. The intermediate iminophosphoranes, CH2CH(CH2)9N=P(2-py)3, CH2CH(CH2)9N=P(Ph)- (2-py)2, CH2CH(CH2)9N=P(Ph)2(2-py) and CH2CH(CH2)9N=PPh3 were isolated by design and their hydrolyses in both acidic and basic environments were carefully studied. While all four compounds followed the expected route of a P=N cleavage to give CH2CH(CH2)9NH3+ and phosphine oxides in acidic environments. Hydrolyses of the iminopyridlphosphoranes CH2CH(CH2)9N=P(Ph)n(2-py)2-n (n = 0, 1, 2) under basic conditions produced an N-substituted phosphinic amide, CH2CH(CH2)9NHP(O)(Ph)n(2-py)2-n and a free pyridine via a P-C cleavage. The pyridylphosphorane with e-donating OMe-substituent, CH2CH(CH2)9N=PPh(2-py-4-OMe)2, hydrolyzed in a much slower rate as compared to its parent pyridylphosphoranes. On the contrary, the phenylphosphoranes with e-withdrawing halide-substituents, CH2CH(CH2)9N=P(4-X-Ph)3 (X = F, Cl), hydrolyzed in a noticeably faster rate with reference to their nonsubstituted counterpart. Three different palladium catalysts with a stable metallahexacycle formed around the Pd center were synthesized by the complexation of phosphinic amide ligand with Pd(CH3CN)2Cl2. The soluble, molecular HOCH2(CH2)10NHP(O)(2-py)2PdCl2 catalyzed Heck-type reactions of iodobenzene and acrylates and/or styrene very efficiently to give TOF values of 10,000-17,000 h-1. Both SiO2-supported homogeneous and heterogeneous, (O)3Si−(CH2)11NHP(O)(2-py)2PdCl2, are effective and regioselective catalysts for [2+2+2] alkyne cyclotrimerization reactions and can be successfully reused up to the sixth cycle without the problem of losing activity. In the third chapter, the based-catalyzed hydrolysis of two different phosphine oxides O=PX3 (X = 2-pyridy, phenyl) were carefully studied. The mixed phenyl/pyridyl phosphine oxides O=PPhn(2-py-X)3-n, where X = H, n= 1, 2; X= Me, OMe, n = 1, were hydrolyzed in the presence of base to give [HO(O)PPhn(2-py-X)2-n] and pyridine as products. The results of kinetic study showed that the rate of hydrolysis would decrease while the number of phenyl group increases as follows: O=P(2-py)3> O=PPh(2-py)2> O=PPh2(2-py). However, the measured reaction barriers for hydrolyses were found to be increased when the H atom at the para-position on the pyridyl group of O=PPh(2-py)2 replaced with the e-donating groups, OMe or Me. The rates of hydrolyses were in the following order: O=PPh(2-py)2> O=PPh(2-py-4-Me)2 > O=PPh(2-py-4-OMe)2. For phenyphosphine oxides O=P(4-Ph-X)3, where X = F and Cl, the hydrolyses can be carried out to give [HO(O)P(Ph-X)2-n] and halogenated benzene as products. The hydrolysis rates for this series of phenylphosphine oxides were found in the following order: O=P(Ph-F)3> O=P(Ph-Cl)3> O=PPh3. The parent triphenylphosphine oxide, however, would not undergo hydrolysis even at temperature of 190 oC for days. The energy barriers of the based-catalyzed hydrolysis were calculated by using HF/6-31+G* and B3LYP/6-31+G* level of theory, and the results were consistent with the experimental observation. We found that the energy barriers for the hydrolyses followed the similar trend shown below in its decreasing order: O=P(2-py)3> O=PPh(2-py)2> O=PPh(2-py-4-Me)2 > O=PPh(2-py-4-OMe)2 > O=PPh2(2-py)> O=P(Ph-F)3> O=P(Ph-Cl)3> O=PPh3. In the last chapter, the catalytic reactivity of tungsten Lewis acid [P(2-py)3W(CO)(NO)2]2+ toward Diels-Alder reaction of cyclopentadiene and methyl vinyl kentone and/or 1,3-cyclohexadiene and methyl vinyl kentone were discussed. Comprehensive kinetic measurements of both the uncatalyzed and the corresponding 1-catalyzed Diels-Alder reaction of cyclopentadiene and methyl vinyl kentone as well as cyclohexadiene and methyl vinyl kentone were conducted at various temperatures. Based on the results of these kinetic works, we were able to obtain lavish information to quantify the catalyst efficiencies. For example, the activation energies, preexponetial factors, entropies of the transition state, the reaction rate constants, and reaction order were determined. According to these results, a reasonable mechanism and the reaction rate determining step of the 1-catalyzed Diels-Alder reactions of cyclopentadiene and methyl vinyl kentone as well as cyclohexadiene and methyl vinyl kentone were therefore suggested. The experiment of this chapter is research of continuing the laboratory schoolmate, so does not do the detailed discussion in this thesis, only publish it the thesis and examine and enclose it in the appendix.

Secondary phosphine oxides (SPOs) are air-/moisture-stable and are advantageous for the purpose of storage. They might act as preligands towards transition metals after conversion to its tautomeric form, Phosphinous Acid (PA). Palladium complexes A-C were obtained from the reactions of Pd(II) with some selected secondary phosphine oxides (SPOs) and imines. The same chemical formula of palladium complex C with two different orientations of ligands were determined by single-crystal X-ray diffraction methods. Direct C-H functionalization of benzoquinone (BQ) was observed from the reaction of it with secondary phosphine oxides plus imines and in the presence of oxidant Ag+. Through this method, a variety of benzoquinone derivatives with both C-N and C-P bond formations on BQ were achieved in one-pot reaction and with high yields. The yields of the C-H functionalization of benzoquinone were enhanced by the extra addition of certain amount of Pd(OAc)2. Similar C-H functionalization on naphthoquinone (NQ) was also observed. A mechanism was proposed to account for the formations of all the quinone derivatives. It is believed that the reaction does not undergo a radical reaction pathway, as reported in many related works.

In this work, the synthesis and characterization of several quinone derivatives with specific configurations were described. Stoichiometric amount of silver carbonate was employed and the C-H activation on the quinone was observed. Crystal structures of several newly-made quinone derivatives were determined by X-ray diffraction methods. These novel quinone derivatives having both phosphine group(s) and amine functional group(s) might act as P,N-bidentate ligands toward transition metals and form metal-containing pre-catalysts. The potential of these pre-catalysts in catalysis is worthy of exploring in the future.
