Treatment of these bis(ethynyl)platinum complexes with HgCl2 specifically removes the ethynyl trans to L, reforming (II) and the ethynylmercury(II) chloride. Reactions of the bis(ethynyl)mercurials can be advantageously carried out in the presence of [NEt4]Cl, which symmetrises the Hg(CCR)Cl by-product to Hg(CCR)2(thus making both ethynyls available for transfer to platinum) and [NEt4]2[Hg2Cl6](which

Site migrations of resident ethynl groups during formation and exchange reactions of [Pt(CCme)(CCPh)(CO)PmePh2] provide evidence for the operation of Oxidativeaddition–reductiveeliminationsequences.
