Abstract
There is no precedent for the usage of transition metal carbamoyl complexes (typical hydrogenase mod-els) as pre-catalysts for oxidation or CO2 utilization purposes. In this work, we describe that carbamoyl-Mn(I) complexes are capable of selectively catalyzing both epoxidation of olefins and epoxides with car-bon dioxide to form cyclic carbonates. The dual-role catalytic system was well adapted to a wide range of aromatic olefins, and the desired cyclic carbonates were obtained in moderate to excellent yields. Mechanistic investigations indicated that active Mn(II)-oxo and Mn(III)-oxo species were involved in the oxidation process.(c) 2023 Elsevier Inc. All rights reserved.
