摘要：

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 H-1, C-13, Si-29, and sip 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'M-2(mu(2)-O)(2)P(OSiMe3)(2)](2) (R'M-2 = Me2Al (8), Et2Al (9), and Me2Ga (10)). The molecular structures of 8 and 9 were confirmed by X-ray crystallography.
