Complexes of 2,6-Disubstituted 1-Oxa-4-thia-3,5-diazine 4,4-Dioxides with Symmetric Triazines as Supramolecular Systems. Preparation and Properties

Reactions of 2,6-disubstituted 1-oxa-4-thia-3,5-diazine 4,4-dioxides with substituted cyanamides in aromatic solvents (benzene, toluene, chlorobenzene, benzonitrile) furnished stable complexes including 1-oxa-4-thia-3,5-diazine4,4-dioxide, symmetric triazine, and solvent (or no solvent) in a ratio 2 : 2 : 1. The molecules involved in the complexes are joined by intramolecular forces into a unified energetically favorable supramolecular system.__________Translated from Zhurnal Organicheskoi Khimii, Vol. 41, No. 2, 2005, pp. 297–300.Original Russian Text Copyright © 2005 by Shishulina, Sazhina, Michurin.
