Selective Displacement of a Triphenylphosphine Ligand in Triorgano-(triphenylphosphine)gold(III) with Alkyl Lithiums Affording Tetraalkylaurates(III)

Article abstract of DOI:10.1246/cl.1988.63

Reactions of cis- and trans-dimethylethyl(triphenylphosphine)gold(III) with ethyl lithium selectively afford anionic square planar cis- and trans-dimethyldiethylaurates(III), respectively.On hydrolysis, the former gives cis-methyldiethyl(triphenylphosphine)gold(III), whereas the latter trans-dimethylethyl(triphenylphosphine)gold(III).
