Photolysis of trans-1,2-difluoro-1,2-di-iodoethene with 248 nm radiation from an excimer laser yielded difluoroethyne, cis-1,2-difluoro-1,2-di-iodoethene and 1,2,3,4-tetrafluoro-3,4-di-iodocyclobutene. Potential pathways for these products are presented in terms of the energetics of the reaction, and the dependencies of product formation on pressure and extent of conversion are discussed.
