Octahedral metal carbonyls. X. Kinetics of the reactions of [1,2-bis(diphenylphosphine)ethane]chromium- and molybdenum tetracarbonyls with lewis bases☆☆☆

Add time:08/18/2019    Source:sciencedirect.com

Kinetic data for the reaction of Lewis bases (L) with (diphos)M(CO)4 (diphos = 1,2-bis(diphenylphosphino)ethane; M = Cr, Mo) support a mechanism in which reversible dissociation of CO is followed by attack of L on the resulting five-coordinate intermediate. Activation parameters for the carbonyl dissociation step have been calculated. The results suggest metal π-base and ligand π-acid interaction in the ligand association step. The results are compared to those previously obtained for reactions of L with (bidentate)M(CO)4 systems.
