  Chemistry of Some Dihalogallium(III) β-Diketonate Derivatives. Crystal and Molecular Structures of GaCl₂(acac), GaCl₂(tmhd), and [trans-Ga(acac)₂(THF)₂⁺][GaCl₄^-]

  摘要：

  The dichlorogallium(III) beta-diketonato derivatives GaCl2(bdk) [bdk = acac (2,4-pentane-dionato) and tmhd (2,2,6,6-tetramethylheptanedionato)] have been prepared and characterized in hydrocarbon solutions by NMR spectral studies and cryoscopic molecular weight measurements and in the solid state by X-ray structural studies. These compounds, which have chelated beta-diketonato ligands and four-coordinate gallium, react with THF to form species of composition GaCl2(bdk).THF. A single-crystal X-ray diffraction study identified GaCl2(acac).THF as the ion-pair [trans-Ga(acac)(2)(THF)(2)(+)] [GaCl4-]. The gallium atom in the cation is six-coordinate, whereas in the anion it is four-coordinate. Variable-temperature H-1 NMR spectral studies in CD2Cl2 solution suggest that multiple processes including (i) a stereochemical rearrangement, (ii) THF exchange, and (iii) equilibria between [Ga(bdk)(2)-(THF)(2)(+)] [GaCl4-], GaCl2(bdk), and at least one other species such as [Ga(bdk)(2)(THF)(+)][GaCl4-] are occurring in solution. In contrast, GaX2(hfac) (X = Cl, Br; hfac = 1,1,1,5,5,5-heaxafluoro-2,4-pentanedionato) cannot be isolated because these compounds undergo ligand redistribution reactions to form Ga(hfac)(3) (similar to80% yields).

• Fractional sublimation of the β-diketone chelates of the lanthanide and related elements

  thermally stable and volatile and could be quantitatively recovered by vacuum sublimation below 140°. The volatility of the HFAA and DPM lanthanide chelates increased with an increase in atomic weight (a decrease in ionic radii) of the lanthanides. The lack of volatility observed for the lanthanide AA and TFAA chelates is attributed to the fact that only hydrates of the chelates were formed, which decomposed

  Reaction of (ferrocenylmethyl)trimethylammonium iodide with the mono-sodium salts of a range of acyclic 1,3-diketones leads smoothly to 2-(ferrocenylmethyl)-1,3-diketones [(C5H5)Fe(C5H4)CH2]CH(COR1)(COR2), but with the corresponding tetrabutylammonium salts deacylation occurs. With the sodium salt of cyclohexane-1,3-dione, disubstitution occurs to give (2,6-dioxocyclohexane-1,1-diyl)bismethyleneferrocene
