Abstract

Treatment of W(CPh)X(CO)₂(PMe₃)₂,1 (a, X = Cl; b, X = Br) with neat PMe₃ for several days gives W(CPh)X(CO)(PMe₃)₃,2a and 2b. The ketenyltungsten complexes W(OCCPh)X(CO)(PMe₃)₃ are intermediates in this reaction. The complex W(OCCPh)Cl(CO)(PMe₃)₃ was isolated and characterized spectroscopically. Treatment of complex 2a with neat pyridine at 75 °C for several hours yields W(CPh)Cl(CO)(py)(PMe₃)₂·.
