Reaction of [AuCl(tht)] (tht = tetrahydrothiophene) with 2-(4′,5′-dihydro-4′,4′-dimethyl-2′-oxazolinyl) thien-5-yllithium or 2-(4′,5′-dihydro-4′,4′-dimethyl-2′-oxazolinyl) thien-3-yllithium afforded thienyl dimeric and trimeric oligomers of gold(I). Protonation of these compounds as well as the stable monomers obtained from [Au(C6F5)(tht)] or [AuCl(PPh3)] afforded unique diorganocarbene complexes as well as nitrogen-donor compounds, the former being unusual divinylcarbene complexes. Reaction of 2-(2′-pyridyl)thien-5-yllithium with [AuCl(PPh3)] produced, upon alkylation, organothiocarbene compounds. The molecular structure of the dimeric compound [Au{C=C(C=NCMe2CH2O)SCH=CH}]2 shows a Au?Au separation of 2.8450(6) ?.
