Abstract

The reaction of alkynylselenolatoalkylidynes [W(CSeCCR)(CO)₂(Tp∗)] (R = SiMe₃, SiⁱPr₃, Ph, p-tolyl, ^tBu, CPh₃, SiPh₃, GePh₃; Tp∗ = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with [AuCl(L)] (L = tetrahydrothiophene, SMe₂) readily furnishes heterobimetallic complexes [WAu(μ-CSeCCR)Cl(CO)₂(Tp∗)] where gold(i) chloride coordinates to the tungsten-carbon multiple bond. Alternatively, desilylation of the SiMe₃ complex [W(CSeCCSiMe₃)(CO)₂(Tp∗)] in the presence of gold phosphine complexes [AuCl(PR′₃)] (R′ = Ph or Cy) furnishes the gold alkynyl derivatives, [W(CSeCCAuPR′₃)(CO)₂(Tp∗)].
