Reaction of bistrifluoromethylaminosulphenyl chloride with unsymmetrical fluoro-olefins in daylight or under photochemical conditions gives both possible 1:1 adducts (ca. 1:1 ratio) arising from homolytic fission of the SCl bond. Addition to octafluorobut-2-ene and hexafluorobut-2-yne gives mixtures of the syn- and anti- adducts.
