โœฆ Synopsis

The thermal decomposition of 1,4-dithiin sulfoxides has been known for a Chem., 38, 2419 (1973); K. Praefcke and C. Weichsel, Liebign Ann., 333 (1980), and references cited therein.

Thermally, dithiines may react as dienophiles in [ 2 + 4] -cycloadditions. Photochemically, they afford [ 2+ 2 ] -cyclodimerization products in the absence of oxygen ; in its presence, they are degraded to CO2 and H2S among other photooxidation products. CT-complexes occur with tetracyanoethylene, m

Bis(2,4-diaryl-3-thienyl) disulfide was isolated in the thermal decomposition of 2,5-diaryl-1,4-dithiin. The formation of the rearranged product as well as the kinetic data suggest strongly the valence isomerization of 2,5-diaryl-1,4-dithiin in the course of the decomposition.
