The significance of phosphoniocarbynes in halocarbyne cross-coupling reactions

Author affiliations

Abstract

Competent intermediates in palladium(0)–copper(I) mediated catalytic cross coupling reactions of the bromocarbyne complex [W([triple bond, length as m-dash]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.
