Structure of Co2(CO)6(dppm) and Co2(CO)5(CHCO2Et)(dppm) (dppm = Ph2PCH2PPh2) and exchange reaction with 13CO: An experimental and computational study

The Co2(CO)6(dppm) and Co2(CO)5(CHCO2Et)(dppm) complexes have been synthesized and characterized by liquid- and solid-state NMR spectroscopy and X-ray crystallography. The kinetics of the 13CO incorporation has been measured by means of IR spectroscopy. Theoretical calculations have been taken in order to explore the mechanisms of CO dissociation reactions and the intramolecular rearrangements.
