  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.

  monomeric gallium(III) compounds, each containing three different ligands, have been prepared by metathetical and/or ligand redistribution reactions and identified as single compounds in benzene solution and in the solid phase, as appropriate. These compounds include GaRCl(acac) (R = Me, Et, Mes (mesityl, C6H2Me3); acac = 2,4-pentanedionato), GaCl[N(SiMe3)2](acac), and GaMe[N(SiMe3)2](acac). X-ray structural

  通过复分解和/或配体再分布反应已制备了五种单体镓（III）化合物，每种化合物包含三个不同的配体，并视情况在苯溶液和固相中鉴定为单一化合物。这些化合物包括GaRCl（acac）（R = Me，Et，Mes（mesityl，C 6 H 2 Me 3）; acac = 2,4-pentanedionato），GaCl [N（SiMe 3）2 ]（acac）和GaMe [N（SiMe 3）2 ]（acac）。GaMeCl（acac）和GaCl [N（SiMe 3）2的X射线结构研究]（acac）证实了在这些单体分子中存在与镓键合的三种不同的配体。还制备和表征了相关的衍生物GaMeCl（hfac）和GaMesCl（hfac）（hfac = 1,1,1,5,5,5-六氟戊二酮），但这些化合物在室温下缓慢分解。
