Abstract: A series of aromatic acids has been tested as additives for the platinum-catalyzed hydrosilylation of styrene with triethoxysilane.Both excellent conversion of styrene and selectivity in favor of the β-adduct were achieved using aminobenzoic acids as additive.Moreover,the use of 4-aminobenzoic acid led to significantly superior enhancement in both catalytic activity and selectivity among the tested aminobenzoic acids.Indeed,100% conversion of styrene and 98.4% selectivity in favor of the β-adduct were obtained.Additionally,hydrosilylations of various alkenes with a variety of platinum catalysts have also been tested,and in each case the conversion of substrate and the selectivity of the β-adduct were promoted by using 4-aminobenzoic acid as additive.

Key words: hydrosilylation, platinum catalyst, aminoaromatic acid, additive
