The title compounds have been analyzed by 13C NMR spectroscopy and compound with the N-3 methyl and O/S alkyl derivatives. The mesoionic structures 2a,b are rejected in favour of 1a,b on the basis of the C5=CH coupling constants and the chemical shif

5-Azidotriazoles bearing a thiazole, benzothiazole or pyridine ring at the 4-position were synthesized and thermolyzed at 60°C. Whereas the 5-azido-4-(thiazol-2-yl)triazole 4 decomposed with extrusion of nitrogen and formation of the triazene 5 as t

Rate measurements for thermolysis of 4-azidothiazoles in p-xylene solution have identified neighbouring group effects from nitro (19-fold rate increase), phenyliminomethyl (16), formyl (4.5) and acetyl (2.2) substituents in the 5-position. These effe
