Hydridoplatinum(<scp>II</scp>) Complexes with Phosphites and Phosphonites and their Reactions with Methyl Acrylate

Abstract

High reactivity and regioselectivity in alkene insertions characterize the novel complexes 1, LP(OMe)3 or PMe(OMe)2. They can readily be prepared by reduction of cis-PtCl2L2 with NaBH4. Irrespective of the solvent used, methyl acrylate always adds to 1 as a branched ligand. Apart from 2, complexes 1 LPEt3, also afford the isomer with the linear ligand.
