Abstract:
Films containing the metals copper, yttrium, calcium, strontium, barium, and bismuth were grown by organometallic chemical vapor deposition (OMCVD). Depositions were carried out at atmospheric pressure in an oxygen-rich environment using metal beta-diketonates and triphenylbismuth. The films were characterized by Auger electron spectroscopy, Nomarski and scanning electron microscopy, and x-ray diffraction. The results show that films containing yttrium consisted of Y2O3 with a small amount of carbidic carbon, those with copper and bismuth were mixtures of oxides with no detectable carbon, and those with calcium, strontium, and barium contained carbonates. Use of a partially fluorinated barium beta-diketonate gave films of BaF2 with small amounts of BaCO3.

Abstract:
The application of non-phosphine-based chelating ligands in homogeneous catalyst systems is a surprisingly recent and relatively unexplored area of research. Chelating ligands can concurrently stabilize intermediates, control catalyst activity and direct the product distribution far more effectively than monodentate ligands. In this review our studies with catalyst systems containing chelate ligands primarily of the β-diketonate type [dithio-β-diketonate (sacsac); monothio-β-diketonate (sacac); and imino β-diketonate (nacac) ligands] is discussed. Examples of the catalyst systems show enzyme-like superactivity. Studies modelling these catalyst systems have provided valuable information relating the effects of ligand modifications to reaction pathways and to activities. Our most recent investigations of simple chelating ligands based on picolinic acid are also discussed. Studies modelling CO/ethene insertion/elimination with extremely labile alkylplatinum picolinate complexes led to the development of new single-component nickel oligomerization catalysts.

Abstract:
Mixed multidentate linkers with donor groups of different types can be fruitfully exploited in the self-assembly of coordination polymers (CPs) and Metal-Organic Frameworks (MOFs). In this work we develop new ligands containing a β-diketone chelating functionality, to better control the stereochemistry at the metal center, and tetrazolyl multidentate bridging groups, a combination not yet explored for networking with metal ions. The new ligands, 1,3-bis(4-(1H-tetrazol-5-yl)phenyl)-1,3-propanedione (H3L1) and 1-phenyl-3-(4-(1H-tetrazol-5-yl)phenyl)-1,3-propanedione (H2L2), are synthesized from the corresponding nitrile precursors by [2+3] dipolar cycloaddition of azide under metal-free catalytic conditions. Crystal structure analysis evidences the involvement of tetrazolyl fragments in multiple hydrogen bonding giving 2D and 1D supramolecular frameworks. Reactivity of the new ligands with different metal salts indicates good coordinating ability, and we report the preparation and structural characterization of the tris–chelate complex [Fe(HL1)3]3− (1) and the homometallic 2D CP [ZnL2(DMSO)] (2). In compound 1 only the diketonate donor is used, whereas the partially deprotonated tetrazolyl groups are involved in hydrogen bonding, giving rise to a 2D supramolecular framework of (6,3)IIa topological type. In compound 2 the ligand is completely deprotonated and uses both the diketonate donor (chelating) and the tetrazolate fragment (bridging) to coordinate the Zn(II) ions. The resulting neutral 2D network of sql topology shows luminescence in the solid state, which is red shifted with respect to the free ligand. Interestingly, it can be easily exfoliated in water to give a luminescent colloidal solution.

Abstract:
Metal-organic assemblies have received significant attention for catalytic and other applications, including gas and energy storage, due to their porosity and thermal/chemical stability. Here, we report the synthesis and physicochemical characterization of three metallosupramolecular assemblies consisting of isomeric ambidentate pyridyl-β-diketonate ligands L1–L3 and Cu(II) metal ions. It has been demonstrated that the topology and dimensionality of generated supramolecular aggregates depend on the location of the pyridine nitrogen donor atom in L1–L3. This is seen in characterization of two distinct 2D polymeric assemblies, i.e., [Cu(L1)2]n and [Cu(L2)2]n, in which both β-diketonate and pyridine groups are coordinated to the Cu(II) center, as well as in characterization of the mononuclear 1D complex Cu(L3)2, in which the central atom is bound only by two β-diketonate units.

Abstract:
The metal polymers based on mono- and heteroligand β-diketonate complexes of Yb(III) with 2,7-dimethyl-octen-1-dione-3,5, 2,6-dimethyl-heptene-1-dione-3, 5 and with phenanthroline was synthesized. It has been defined that the coordination environment of the central ion remains unchanged during radical polymerization. The shape and position of the bands in the electronic absorption spectra are similar to the corresponding monomeric β-diketonate metal complexes, and slight shifts indicate deformation of the elementary unit of the metal polymer during the formation of the polymer chain. It is shown that the polymerization process lead to an increasing in the thermal stability of polymer complexes in comparison with monomeric analogues. An increase in the emission of metal polymers in comparison with monomeric complexes was established by the method of luminescent spectroscopy, which is due to energy, steric, and structural-mechanical factors.

Abstract:
Abstractβ-Diketimines, encountered frequently as “nacnac” ligands, have emerged as popular motifs among other ancillary supports. There has been a great deal of interest in these compounds as supporting ligands because of their strong binding to metal ions, their tunable steric and electronic effects, and their diversity in terms of bonding modes. A classical synthetic approach towards β-diketimines is direct condensation of pentane-2,4-diones (and 1,3-diketone analogues) with suitable amines in the presence of an acid source. Recent developments involve the use of molecular sieves to avoid purification problems and to improve yields. Herein, a thorough survey of the synthetic approaches to β-diketimine ligands and their metal complexes, and applications in coordination chemistry, has been compiled.

Abstract:
Yasutaka Ishii of Kansai University has developed (J. Org. Chem. 2007, 72, 8820) a novel route to furans, using a mixed-metal catalyst to effect condensation of an aldehyde or 1,3 diketone such as 1 with an acceptor such as 2 to give the 3-furoate 3. In a complementary approach, Yong-Min Liang of Lanzhou University has found (J. Org. Chem. 2007, 72, 10276) that diazoacetate 5 will condense with an alkynyl ketone to give the 2-furoate 6. David W. Knight of Cardiff University has shown (Tetrahedron Lett. 2007, 48, 7709) that an alkynyl diol such as 7, readily available by dihydroxylation of the corrresponding alkenyl alkyne, cyclized to the furan on exposure to AgNO3 on silica gel. Professor Knight has also (Tetrahedron Lett. 2007, 48, 7906) established a route to poly-substituted pyrroles 10, by iodination of alkynyl sulfonamides such as 9. Similarly, Richard C. Larock of Iowa State University found (J. Org. Chem. 2007, 72, 9643) that I-Cl cyclized methoximes such as 11 to the corresponding iodo isoxazole 12, and Stephen L. Buchwald of MIT uncovered (Organic Lett. 2007, 9, 5521) the cyclization of an enamide such as 13 with I2 to the corresponding oxazole 14. In developing a more efficient route to a new class of materials that he has named “triazolamers”, Paramjit S. Arora of New York University was able (J. Org. Chem. 2007, 72, 7963) to effect diazo transfer to the amine 15 and subsequent condensation with 16 to give 17, without isolation of the intermediate azide. C. V. Asokan and E. R. Anabha of Mahatma Gandhi University have described (Tetrahedron Lett. 2007, 48, 5641) the activation of a ketone 18 followed by condensation with malononitrile 19 to give the pyridine 20. Hans-Ulrich Reissig of the Freie Universität Berlin has established (Organic Lett. 2007, 9, 5541) a complementary three-component coupling of a nitrile 21 with the allenyl anion 22, followed by a carboxylic acid 23 to deliver the pyridine 24. Akio Saito and Yuji Hanzawa of the Showa Pharmaceutical University have reported (Tetrahedron Lett. 2007, 48, 6852) the intramolecular Rh-catalyzed cyclization of a methoxime lactone such as 25 to the pyridine 26.
