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.
