Abstract

Competent intermediates in palladium(0)-copper(i) mediated catalytic cross coupling reactions of the bromocarbyne complex [W(CBr)(CO)₂(Tp∗)] (Tp∗ = hydrotris(dimethylpyrazolyl)borate) have been isolated however heterobimetallic phosphoniocarbyne complexes [WPd(μ-CPPh₃)Br(CO)₂(PPh₃)_x(Tp∗)] are identified as productive (x = 1) or non-productive (x = 0) tangents to the catalytic cycle.
