Synthesis and properties of fac-Re(dmbpy)(CO)3CHO (dmbpy = 4,4′-dimethyl-2,2′-bipyridine), a possible intermediate in reductions of CO2 catalyzed by fac-Re(dmbpy)(CO)3Cl

Abstract

Synthesis of fac-Re(dmbpy)(CO)₃CHO 2 and its reactions with CO₂ in DMF and DMSO have been conducted; 2 transfers hydride to CO₂ to give Re(dmbpy)(CO)₄⁺ OCHO⁻ 5 which is rapidly transformed to fac-Re(dmbpy)(CO)₃- (OCHO) 3 in DMF, thus supporting the viability of 2 in photocatalytic reactions of fac-Re(dmbpy)(CO)₃Cl with CO₂.
