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.
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.
