An efficient Pd-catalyzed route to silyl esters

A one step, highly selective catalytic route to silyl esters is reported. C ommercially available silanes with Si-H functionality were converted to sil yl or siloxy esters in the presence of Pd(OAc)(2) under mild reaction condi tions. This protocol was found to be equally applicable for the modificatio n of multiple silicon centers in one framework and lead to the correspondin g polysilyl esters in high yields, A comparison of catalytic efficiency of Pd(OAc)(2) versus Pd on carbon was also undertaken.
