Preparations and reactions of trifluoromethylthiocopper

Abstract

Abstract Trifluoromethylthiocopper, a versatile reagent for the introduction of the trifluoromethylthio group into organic compounds, has been prepared in a crystalline form. The thiyl radicals, generated in situ from this precursor, cause the cleavage of the 3S bond of di‐ and trisulfides to give unsymmetrical di‐ and trisulfides. Unsymmeirical n‐butyl trifluoromethyl disulfide is formed by the cleaveage of the CS bond of n‐butyl sulfide.
