摘要：

GRAPHICS A combination of palladium acetate and the imidazolium salt IPr-HCl (1, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) has proven to be highly efficient in the cross coupling reactions of aryl bromides and electron deficient aryl chlorides with phenyltrimethoxysilane or vinyltrimethoxysilane. The catalytic performance of this system was found to be comparable to that of systems using PCy3 and P(o-tol)(3).
