Abstract

Treatment of a CpWOs₃(CO)₉(μ-O)(μ₃-CCH₂Tol) (1) with excess trimethylphosphite in boiling toluene afforded both an addition product, CpWOs₃(CO)₉(P(OMe)₃)(μ-O)(μ₃-CCH₂-Tol) (3), and a substitution product, CpWOs₃(CO)₈(P(OMe)₃)(μ-O)(μ₃-CCH₂)Tol) (4), isolated as crystalline solids in 32% and 21% yields, respectively. From an analogous reaction of 1 with diphenylmethylphosphine only the substitution product CpWOs₃(CO)₈ (PPh₂Me)(μ-O)(μ₃-CCH₂Tol) (5) was isolated. Complexes 3-5 have been characterized by IR, ¹H and ¹³C NMR, and field desorption mass sepctroscopies. In addition the molecular structure of 5 has been determined by X-ray crystallography.
