Stereochemical consequences of transannular S–Cl ⋯ S interactions in sulphur nitrogen chemistry; preparation and structure of [(Me2N)2C2N4S2Cl]+[Cl3]–

Abstract

The oxidation of 3,7-bis(dimethylamino)-1,5-dithia-2,4,6,8-tetrazocine yields the S-chloro salt [(Me₂N)₂C₂N₄S₂Cl]⁺[Cl₃]^–, whose crystal and molecular has been determined by X-ray crystallography; the molecular structure of the cation and the cation–anion contacts are related to the stereochemistry of chlorination of transannular sulphur–sulphur interactions in cyclothiazenes.
