Article abstract of DOI:10.1021/om00138a037

Methods for the synthesis of X(CO)[P-(OMe)₃]₃M≡CPh (M = Cr, X = Br; M = Mo, W, X = Cl) and Cl[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.
