The palladium-mediated reaction of [W(鈮Br)(CO)₂(Tp*)] (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with primary phosphines PH₂R (R = Ph, Cy) affords the secondary phosphinocarbyne complexes [W(鈮PHR)(CO)₂(Tp*)], deprotonation of which provides the anionic phosphaisonitrile complexes [W(CPR)(CO)₂(Tp*)]^{鈭?/sup>, including the structurally characterized salt [W(CPPh)(CO)₂(Tp*)][K(kryptofix)].}
