The reaction of hexacarbonylvanadium with aromatic hydrocarbons

Article abstract of DOI:10.1021/ic50019a001

Hexacarbonylvanadium reacts with benzene, toluene, p-xylene, and mesitylene to give the red crystalline [V(CO)₄(arene)]-[V(CO)₆]. The corresponding hexafluorophosphates and tetraphenylborates [V(CO)₄(arene)]X (X = PF₆^-, [B(C₆H₅)₄]^-) have been prepared by metathetical reactions in tetrahydrofuran. The infrared spectra of these compounds in the CO stretching region are presented and a mechanism of formation of [V(CO)₄(arene)][V(CO)₆] is proposed. Copyricht 1964 by the American Chemical Society.
