A novel reaction of thiirane cation radicals in solution: the formation of 5,6-diphenyl-1,2,3,4-tetrathianes through trisulphurated thiirane cation radical intermediates
Abstract
A novel reaction of thiirane cation radicals to form cis- and trans-5,6-diphenyl-1,2,3,4-tetrathianes [cis-(2) and trans-(2)] took place when cis- and trans-2,3-diphenylthiiranes [cis-(1) and trans-(1)] were mixed with a catalytic amount of tris(p-bromophenyl)aminium hexachloroantimonate (3) in dichloromethane.
