Abstract
The present study relates to a heterogeneous polyimide-supported transition metal complex catalyst for hydrosilylation reactions, which is prepared by functionalizing a heat- and acid-resistant polyimide resin with a homogeneous metal catalyst of ruthenium (II) complex. The heterogeneous polyimide-supported transition metal complex catalyst of the invention provides superior catalytic activity, selectivity and stability in the hydrosilylation of acetophenone. Further, the catalyst has strong resistance against heat and acid. Besides, the catalyst of the invention may provide the following advantage which are critical in industrial use: it can be easily separated from the reaction product, which eases recycling of the catalyst.
