Desulfinylation of Ag(I) Sulfinyl Mesoionic Carbenes: Preparation of C‑Unsubstituted Au(I)–1,2,3-Triazole Carbene Complexes

New and well-characterized Ag–bis­(1,2,3-triazolylidene) complexes having enantiopure (S)-sulfoxides upon sequential treatment with alcohols and Au­(I) form separable mixtures of regioisomeric C-unsubstituted Au–1,2,3-triazolylidene complexes. Mechanistic studies and DFT calculations support a desulfinylation process for in situ generated free triazolylidene salts.
