Abstract

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.
