Abstract:

Compounds of the type R2Gabdk RMe, Et, Mes mesityl bdk2,4-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 Mes2Gahfac 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 andor pyridine were also investigated.
