Elemental fluorine reacts with iodine at −75° and the resulting IF is reacted, without any isolation or purification, with olefins thus producing fluoro-iodo compounds in an excellent regio- and stereospecific mode.
1,1,3,3,3-Pentafluoropropene-diethylamine complex (PFPDEA) has been found useful as a fluoride source in halofluorination reactions of various olefins. Reactions proceeded with PFPDEA and N-halosuccinimide (NXS, X = Br, I) or 1,3-dibromo-5,5-dimethylhydantoin (DBH), as sources of electrophilic halogens, in a regioselective manner.
