trifluorovinyl ether (4) with chlorine monofluoride (ClF) gas in aprotic solvent; and alkenes 2, 1H-perfluorohept-1-ene (3E), and 4 with chlorine (Cl2) in protic solvent were investigated. Regiochemical data from SN2-like ring-opening of the intermediate was used to predict the symmetry of the chloronium ion. The chloronium ions from perfluorohydroalkene 2 with two terminal hydrogens were found to be unsymmetrical
