| Abstract: | Methylation of 5-phenylamino-1,2,3-thiadiazole led regiospecifically to mesoionic 3-methyl-5-phenylimino-1,2,3-thiadiazole, its molecular structure was determined by X-ray diffraction analysis. 3-Aryl-5-arylimino-1,2,3-thiadiazoles were obtained by replacement of chlorine in 3-aryl-4,5-dichloro-1,2,3-thiadiazolium perchlorates with excess arylamine. |
