A computational study of the mechanism of the [(salen)Cr + DMAP]-catalyzed formation of cyclic carbonates from CO2 and epoxide†
Abstract
Epoxide and CO2 coupling reactions catalyzed by (salen)CrIIICl have been modeled computationally to contrast a monometallic vs. a bimetallic mechanism. A low-energy CO2 insertion step into the metal–alkoxide bond was located.
