Carbon dioxide activation; formation of trans-(Ph3P)2Rh(CO)(OCO2H) in the reaction of CO2 with HRh(CO)(PPh3)3–CO and the determination of its structure by X-ray crystallography
Abstract
The intermediate produced from the interaction of HRh(CO)(PPh3)3 with CO reacts with carbon dioxide to yield a novel hydrogencarbonate complex, trans-(Ph3P)2-Rh(CO)(OCO2H)(1), whose structure has been established by X-ray crystallography; (1) undergoes reversible loss of CO2
