Le complexe [{PtCl 2(triméthyl-2,4,6-pyridine)} 2] catalyseur homogene d'hydrogenation et d'hydrosilylation d'olefines et d'aldehydes et cetones α,β-insatures

Abstract

The chloro-bridged platinum(II) complex dichlorobis(2,4,6-trimethylpyridine)-platinum was found to be an active catalyst for homogeneous hydrogenation and hydrosilylation of olefins and α,β-unsaturated aldehydes and ketones at room temperature and under atmospheric pressure. Hydrosilylation of terminal olefins can be achieved with dimethylphenylsilane and a catalyst/reactant ratio of 10 −6/1. This complex is the first example of a platinum(II) compound containing pyiridine ligands having good catalytic activity possibilities.
