Direct insertion of a nitrogen atom into the S–S link of a 1,2,3,5-dithiadiazole ring in a D.C. nitrogen glow discharge

Abstract

Solid crystalline bis(4-aryl-1,2,3,5-dithiadiazole), (R[graphic omitted])₂ combines with two radical nitrogen atoms and/or excited nitrogen molecules in a low pressure nitrogen plasma to give bis(5-aryl-1,2,3,4,6-dithiatriazine), (R[graphic omitted])₂ in high yield (R = Ph and p-CIC₆H₄).
