Coupling of Epoxides to Pt^II‐Complexes with Carbon Dioxide and the Structure of a Cyclic Metallacarbonate

Abstract

Model complexes for postulated intermediates in the preparatively important catalytic coupling of CO2 and epoxides to give cyclic carbonates are provided by the compounds 1 ( = bpy, phen; R = H, Ph, CH2OPh). They are formed upon reaction of [PtMe2( )] with epoxides under CO2 atmosphere. In principle, CO2 in the air should be sufficient.
