Mechanistic insights into hydride transfer for catalytic hydrogenation of CO sub(2) with cobalt complexes

The catalytic hydrogenation of CO sub(2) to formate by Co(dmpe) sub(2)H can proceed viadirect hydride transfer or viaCO sub(2) coordination to Co followed by reductive elimination of formate. The different nature of the rate-determining step in the two mechanisms may provide new insights into design...

Zusammenfassung:The catalytic hydrogenation of CO sub(2) to formate by Co(dmpe) sub(2)H can proceed viadirect hydride transfer or viaCO sub(2) coordination to Co followed by reductive elimination of formate. The different nature of the rate-determining step in the two mechanisms may provide new insights into designing catalysts with improved performance.
