Abstract

α-Oxides of all three isomers of hexafluoropropene trimer can be made very conveniently by direct epoxidation of corresponding olefins, using aqueous sodium hypochlorite in the presence of a polar co-solvent (e. g. acetonitrile). Epoxidation proceeds readily and results in high yilds of α-oxides (I–III). The epoxidation reaction's stereochemistry is discussed. ▪ The behaviour of compounds (I–III) in reactions with some nucleophilic (CsF, Et 3N, LiAlH 4, CH 3ONa) and electrophilic (SbF 5, HSO 3F) agents is studied. The effect of steric and electron factors on the reactivity behaviour of these materials will be discussed.
