Abstract

Methods for the synthesis of X(CO)[P-(OMe)₃]₃M≡≡CPh (M = Cr, X = Br; M = Mo, W, X = Cl) and CI[P(OMe₃)]₄M≡≡CPh (M = Mo, W) starting from the acyl complexes [NMe₄] [(CO)₅M–C(O)Ph]are described. Substitution of two or all four trimethyl phosphite ligands in Cl[P(OMe)₃]₄W≡≡CPh by bis(diphenylphosphino)ethane is demonstrated. The crystal structure of Cl[P-(OMe)₃]₄Mo≡≡CPh is reported.
