1,1′,2,2′,3,3′-Tetrathiadiazafulvalenes; preparation and characterisation of trans-[ClCNS2CCS2NCCl]
Abstract
Reduction of 4,5-dichloro-1,2,3-dithiazolylium chloride with two equivalents of triphenylantimony in liquid SO2 affords the 1,1′,2,2′,3,3′-tetrathiadiazafulvalene trans-[ClCNS2CCS2NCCl]; the structural features and redox chemistry of this novel ring system are described.
