Abstract

Title full: Preparation and reactivity of PhP(C5Me4H)2 and Ph2P(C5Me4H). X-ray crystal structures of Mo(CO)5[Ph2P(C5Me4H)] and (η5-C5Me4H)Mo(CO)(μ-PPh2 )2Mo[(η5-C5Me4) P(O)Ph 2](CO) · 1/4C6H14. 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-PPh 2)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.
