Process for preparing cyclic carbonate esters from olefins in a single reaction mixture

摘要

A process for reacting in admixture, an olefin with oxygen, CO, and water, to form a cyclic alkylene carbonate, in the presence of a catalyst composition comprising a catalytically active osmium compound, copper containing co-catalyst I (e.g. CuBr2) and a co-catalyst II (e.g. pyridine) is disclosed.
