Tetrathiadiazafulvalenes; preparation and characterisation of cis- and trans-[RCNS2CCS2NCR](R = Me, Ph)
Abstract
Tetrathiadiazafulvalenes can be prepared by the reductive coupling of 5-methylthio-1,4,2-dithiazolium salts, and thermolysis of the resulting hexathiooxalates; oxidation of tetrathiadiazafulvalenes affords the corresponding radical cations.
