New type of fragmentation of organic cation-radicals in a strong electrical field (in Russian)
A new type of fragmentation of organic cation radicals of sulfides, sulfoxides, and sulfones, leading to the elimination of S/sup +/, SO..mu.. and SO/sub 2//sup +/ ions, respectively, has been discovered, and the possible mechanisms of their formation have been proposed. The most probable is a mechanism by which a cleavage of two C-S bonds takes place in the cyclic transition complex and formation of one C-C bond due to the recombination of the radicals. The line of the ion with a mass of 32 amu present in the spectra of almost all the sulfoxides studies, was assigned to the sulfur ion, formed by a similar mechanism after the displacement of alkyl or aryl residue in the molecular ion from sulfur to oxygen. Signs of such a migration also appear in the mass spectra of certain sulfones.
