On the basis of data of 13C and 1H NMR and IR spectroscopy, it was shown that 2-benzothiazolylhydrazones of aliphatic aldehydes were in solution as a mixture of E and Z isomers, and hydrazones of aromatic aldehydes were in solution only as E isomers.All i

A simple arylhydrazone containing the benzothiazole moiety which may be used as an efficient ligand in the palladium-catalyzed Mizoroki–Heck and Suzuki–Miyaura cross-coupling reactions, under infrared irradiation as an alternative source of energy, is presented. The reactions proceeded with extremely high efficiency under mild conditions and produced very good yields.

Benzothiazole-2-thiol 1 on heating with excess of hydrazine hydrate yields 2-hydrazino-1,3-benzothiazole (2). Compound 2 on reaction with carbon disulfide in alkaline medium affords [1,2,4] triazolo [3,4-b] [1,3] benzothiazole-3-thiol (3). Condensation of 2 with various substituted aryl aldehydes yields corresponding hydrazine derivatives (4), which on cyclisation with acetic anhydride gave corresponding [1,2,4] triazolo [3,4-6] [1,3] benzothiazoles (5). Some other triazolo derivatives (6,7,8) of benzothiazole were obtained by the cyclization of 2 with benzoyl chloride, acetyl chloride and formic acid respectively. Again compound 2 on condensation with acetyl acetone and ethylacetoacetate gives pyrazolo derivatives (9,10) respectively. The synthesized compounds were characterized by elemental and spectral analysis.

Notwithstanding its tendency toward air oxidation in solution, 2-hydrazinobenzothiazole I reacted with aromatic aldehydes in ethanol to give the corresponding hydrazones III-XV in high yields and analytical purity.In related examples, acylation took place
