Abstract The first order reactions of benzyl-molybdenum complexes, [(η5-C5H5)(CO)3Mo(CH2C6H4X)], with triphenylphosphine in acetonitrile to yield the trans-substituted acyl complexes, [(η-C5H5)(CO)2(PPh3)Mo(COCH2C6H4X)], have an overallrate constant which tends towards a limiting value at high triphenylphosphine concentration. The reactivity of the molybdenum-carbon bond is enhanced by electron donating substituents, X, and can be analysed in terms of Hammett substituent parameters. A marked enhancement of rate is observed in dimethylsulfoxide, in which solvent the cis-acyl complex is the unexpected initial product.
