Abstract

The first practical route to substituted carbonyl anions of niobium and tantalum, involving the photolytically induced substitution of mono- and bidentate phosphines into the hexacarbonylmetallate(-I) anions of these metals, has been utilized in obtaining [(C₂H₅)₄N][M(CO)₅P(C₆H₅)₃] and [(C₂H₅)₄N][M(CO)₄- (C₆H₅)₂PCH₂CH₂P(C₆H₅)₂] (M = Nb, Ta). This new pathway also represents the best available method for preparing phosphine, arsine, and stibene substituted carbonyl anions of vanadium; tetraethylammonium salts of [V(CO)₅L]-, where L represents (C₆H₅)₃M (M = P, As, Sb), or (n-C₄H₉)₃P and [V(CO)₄L′]-, where L′ is (C₆H₅)₂PCH₂CH₂P(C₆H₅)₂ or [(C₆H₅)₂AsC₅H₄]₂Fe have been obtained in high yields by this procedure.
