Abstract
One possible ap~ iori product of the thermal condensation of dithiooxamide and an aromatic aldehyde is the unsymmetrical structure I. The reaction, in fact, afforded symmetrical, fully aromatized diarylthiazolothiazoles2 (11). As part of an investigation of possible methods for preparing structures of type I, we studied the condensations of S, S'-disubstituted dithio-
