  Diorganogallium β-Diketonates and Their Lewis Acid−Base Adducts. Crystal and Molecular Structures of Mes₂Ga(hfac) and Me₂Ga(hfac)·NC₅H₅

  摘要：

  Compounds of the type R2Ga(bdk) (R = Me, Et, Mes (mesityl); bdk = 2,4-pentanedionato (acac); 1,1,1-trifluoro-2,4-pentanedionato (tfac), 1,1,1,5,5,5-hexafluoro-2,4-penatedionato (hfac), 2,2,6,6-tetramethyl-3,5-heptanedionato (tmhd)) have been prepared by multiple routes, including hydrocarbon elimination, metathesis, and ligand redistribution reactions, and fully characterized by elemental analyses, cryoscopic molecular weight studies in benzene, and IR and multinuclear NMR spectroscopic studies. An X-ray structural study of Mes(2)Ga(hfac) demonstrated four-coordinate gallium with sigma bonds to the two mesityl rings and to the two oxygen atoms of the beta-diketonate ligand. The Lewis acidities of the diorganogallium beta-diketonate derivatives toward NMe3 and/or pyridine were also-investigated. Two adducts, Me2Ga(hfac). NMe and Me2Ga(hfac). py, were stable to dissociation at room temperature and thus were fully characterized by elemental analysis, cryoscopic molecular weight studies in benzene, vapor pressure-temperature studies, and IR and multinuclear NMR (including variable temperature) spectroscopic studies. The compound Me2Ga(hfac). py was also characterized by an X-ray structural study. The structure involved five-coordinate gallium with one Ga-N, two (inequivalent) Ga-O, and two Ga-C bonds.
