摘要：

Kinetic studies have been performed for the substitution of the first silyl ligand in (Me2N)(3)Ta[Si(SiMe3)(3)](2) (1) by Li(THF)(3)(SiBuPh2)-Ph-t at 233 K (THF = tetrahydrofuran). In the presence of excess Li(THF)(3)(SiBuPh2)-Ph-t, these studies reveal that the reaction likely follows a dissociative pathway. THF, a polar solvent, is found to promote the substitution, and the order of the reaction with respect to THF is 1.7(0.3).
