Abstract
A thiolmethylated crosslinked polystyrene bound platinum complex was prepared and used to catalyze the hydrosilylation of olefins with dichloromethyl silane (DCMS) and diethoxymethyl silane (DEMS). This complex was an active catalyst for the hydrosilylation of styrene and alkyl acrylates, but had no catalytic activity for the hydrosilylation of olefins containing two substituents on a double bond. When used as the catalyst for the addition of DCMS to allyl methacrylate, only 3-methacryloyloxypropyl dichloromethylsilane was obtained. This complex thus catalyzes the hydrosilylation of 1-dodecene or allyl chloride with DCMS, whereas the addition of DEMS to the two olefins would not take place under the same conditions. This catalyst could be used 18 times without appreciable active loss in the hydrosilylation of styrene with DCMS.
