Abstract:	Treatment of complexes of the type M(CO)₄{(Ph₂P)₂CCH₂}] (M = W, Mo or Cr) with functionalized lithium reagents, LiR, followed by hydrolysis gives complexes of the type M(CO)₄{PH₂P)₂CHCH₂R}] in high yields; R = C₆H₄Me-4, C₆H₄OMe-2, C₆H₃(OMe)₂-2,6, C₆H₄OH-2, C₆H₄(COOH)-2, CH₂COPh or CH₂COMe. IR, and ³¹P and ¹H NMR data are given.
