Substitution reaction of W(PhC≡CPh)3(CO) (1) with PMe3 to give W(PhC≡CPh)3(PMe3) (2) has been studied by IR and NMR spectroscopy as well as cross-over experiments. A metastable intermediate W(CO)(PhC≡CPh)2(PMe3)2 (3) is produced by adding two PMe3 moieties into 1 accompanied with loss of a PhC≡CPh ligand. Subsequent conversion from 3 to 2 might involve decarbonylation and PMe3/PhC≡CPh exchange.
