- Abstract
- Mixed phosphonium-iodonium ylides are of interest as reactants for the synthesis of new heterocyclic compounds. Recently it has been shown that the reactions of the phosphonuim-iodonium ylides under the action of light occurs with the formation of radicals. The radicals generated in the photolysis of the ylide itself and the compounds, which are its fragments, diphenyliodonium salt and triphenylphosphine, as well as participating in its reactions, dichloromethane and phenylacetylene, have been studied with the use of PBN and DMPO spin traps. The obtained results have confirmed the radical mechanism of the photodecomposition of the ylide and allowed to specify the composition of primary radicals generated in the photolysis. The unknown magnetic-resonance parameters for some radicals have been determined.
