An interesting entrainment process in S(RN)1 reactions of 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123) with thiolates were studied by experiments and DFT calculations. The radical-anion intermediate, generated from coupling of the fluorinated radical with the thiolate was considered as the key intermediate in this reaction. (C) 2014 Elsevier B.V.

A Facile Synthesis of 1-Chloro-2,2,2-trifluoroethyl Sulfides
2-trifluoroethane (Halothane®) and various aliphatic and aromatic thiols in the presence of sodium dithionite/sodium bicarbonate is described. The synthetic utility of the prepared sulfides is illustrated by the synthesis of biologically potent heterocycles and by their electrophilic reactions with thiophene. thiols - radical reactions - alkylations - fluorinated compounds - sulfides
