摘要：

A series of bis-halo NN-bisdimethylsilylmethylacetamides 1 has been designed and used to investigate the effect of coordination on reactivity at silicon; pentacoordinated SiCl and SiBr bonds are thermodynamically activated towards nucleophilic substitution by N-methylimidazole (NMI) and hexamethylphosphoramide (HMPA), by contrast coordination of R3SiF renders the SiF bond less prone to substitution by nucleophiles than that in the tetracoordinated R3SiF.
