Abstract
Trialkyl phosphates OP(OR)3 (R = Me, Et, Ph, SiMe3) react with AlMe3, AlEt3, and GaMe3 in hydrocarbon solvents to form the adducts Me3Al.OP(OR)3 (R = Me (1), Et (2), Ph (3), SiMe3 (4)), Et3Al.OP(OR)3 (R = SiMe3 (5)), and Me3Ga.OP(OR)3 (R = Me (6), SiMe3 (7)). These products were characterized by 1H, 13C, 29Si, and 31P NMR, infrared (IR), and mass (MS) spectroscopies, and elemental analysis. The trimethylsilyl ester adducts 4, 5, and 7 further undergo a thermally induced dealkylsilylation with the formation of cyclic alumino- and gallophosphate dimers, [R'2M(m2-O)2P(OSiMe3)2]2 (R'2M = Me2Al (8), Et2Al (9), and Me2Ga (10)). The molecular structures of 8 and 9 were confirmed by X-ray crystallography.
