Abstract

The phosphine ligands PhP(C₅Me₄H)₂, I, and Ph₂P(C₅Me₄H), II, can be prepared via the interaction of PhPCl₂ and Ph₂PCl with two and one equivalent(s) of (C₅Me₄H)Li, respectively. At ambient temperature, C₇H₈MO(CO)₄ reacts with I–II to give the corresponding Mo(CO)₅L complex, III–IV [III, L = PhP(C₅Me₄H)₂; IV, L = Ph₂P(C₅Me₄H)], in moderate yield (60–65%). In refluxing hexane, C₇H₈Mo(CO)₄ reacts with II to give (η⁵-C₅Me₄H)Mo(CO)(μ-PPh₂)₂ Mo[(η⁵-C₅Me₄)P(O)Ph₂](CO)· 1/4C₆H₁₄, V, in low yield (10%). Structures of IV and V have been determined by X-ray crystallography.
