CARBON MONOXIDE INSERTION REACTIONS IN SUBSTITUTED CYCLOPENTADIENYLMOLYBDENUM COMPLEXES

Article abstract of DOI:10.1016/0022-328X(85)87471-4

The reactions of <(η⁵-C5Me5)(CO)3MoCH2Ph> and <(η⁵-C5H4Me)(CO)3MoCH2Ph> with tertiary phosphines and alkyl isocyanides in polar solvents to yield phosphine-substituted molybdenum acyl complexes have been explored and compared with the behaviour of the unsubstituted cyclopentadienyl compound.For the pentamethylcyclopentadienyl complex, reaction is restricted to tertiary phosphines with small cone angles.Unlike the cyclopentadienyl system, a mixture of cis- and trans-acyl products is formed.
