N2 - Aminepentacarbonylvanadate(1-) ion undergoes thermal substitution in the presence of π acceptor ligands to provide high yields (65-85%) of V(CO)5L-. By this method [Et4N][V(CO)5Ph2PCH2PPh2], containing an unligated PPh2, [Et4N] [V(CO)5 ((p-ClC6H4)3P)] and the first examples of the isocyanide substituted anions [V(CO)5CNR]-, where R=Me, t-Bu, cyclohexyl and phenyl have been prepared. This new method provides only monosubstituted carbonylvanadate(1-) ions and is especially important when such products are unavailable or not readily preparable by photochemical means.
