The insertion reaction of carbon monoxide, induced by dimethylsulfoxide, into iron-carbon sigma bonds in the complexes, [(η5-C5H5)(CO)2-FeR], has been extended to a wide variety of primary and secondary alkyl substituents. Rate constants for the forward (k1) and reverse (k-1) reactions, together with the second order rate constant (k2), for the further reaction of the solvated acyl complex with triphenylphosphine
