Supported platinum atoms derived catalysts in the hydrosilylation of unsaturated substrates

Abstract

Supported Pt systems, prepared by treatment of supports as carbon, graphite and gamma-Al2O3 with mesitylene solvated Pt atoms, are quite good catalysts for the selective hydrosilylation of 1-hexyne and 2-hexyne to vinyl silanes and of isoprene to allyl derivatives. The catalyst can be recycled for several runs, even months, without loss of activity
