terminal allylic hexafluoroisopropyl sulfides to the internal olefinic sulfide occurs under either photochemical or thermal conditions. In the case of the formation of E and Z isomers, the E isomer was predominant. The rearrangement is suggested as a unimolecular, associative radical mechanism, via kinetic studies, use of inhibitors, or radical initiator.
