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

Abstract

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-pentanedionato-(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 Mes2Ga(hfac) demonstrated four coordinate gallium with sigma bonds to the two mesityl rings and to the two oxygen atoms of the beta-diketonate derivatives toward NMe3 and/or pyridine were also investigated.
