A range of bis(alkylidynyl)phosphines RP{CM(CO)2(Tp∗)}2 (M = Mo, W; R = Cl, Ph, Cy; Tp∗ = hydrotris(dimethylpyrazolyl)borate) are obtained from the reactions of [M(CLi)(CO)2(Tp∗)] with Cl2PR or alternatively via the palladium(0)-mediated reactions of [W(CBr)(CO)2(Tp∗)] with RPH2 (R = Py, Cy). The complexes RP{CW(CO)2(Tp∗)}2 rearrange slowly (R = Cl) or on heating (R = Ph) to afford the isomeric phospha-acyls [W2(μ:η1-C;η2-C,P-CCPR)(CO)4(Tp∗)2].
