Heating CF3C(C2F5)2C(:CF2)CF(CF3)SCH2Ph in CCl4 gave CF3C(C2F5)2C(CF2CH2Ph):CFCF3. The kinetics of rearrangement was examined by crossing reaction, solvent effects, the change of reactant concentration, and trapping experiment The reaction might occur via an intramol. nucleophilic. rearrangement process.
