The reaction of 3,3'-dimethyl-2,2'-bithiazolium salts with potassium superoxide afforded new ten-membered ring compounds 1,2,5,8-dithiadiazecine-6,7-diones in moderate yields.Since these compounds were not obtained from the reaction of KOH-O2 or KOH-H2O2,

In order to establish the structures of compounds described as Δ4-thiazolin-2-ones ten sets of heterocycles (each comprising a 4- or 5-substituted Δ4-thiazolin-2-one, the N-methyl derivative, and the corresponding 2-methoxythiazole) have been examined by i.r., u.v., and 1H and 13C n.m.r. spectrometry.The i.r. results established that in solution the parent compounds exist entirely or predominantly as the 2-oxo-forms.This conclusion is supported by the 1H n.m.r. evidence, but the u.v. and 13C n.m.r. data do not give a clear distinction between the possible 2-oxo- and 2-hydroxy-structures.
