ABSTRACT:
A method for hydrosilylating a vinyl-substituted aromatic compound comprising reacting a hydrido (hydrocarbonoxy)silane compound with the vinyl-substituted aromatic compound in the presence of a platinum or platinum compound catalyst and a carboxylic acid. The presence of the carboxylic acid increases the positional selectivity of addition in the hydrosilylation reaction and reduces the polymerization of vinyl groups even in the case of a high-temperature or long-term hydrosilylation reaction.
