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 hydrazones have been synthesized and evaluated for their in vitro antiproliferative activity against three human cancer cell lines: HL-60 (leukemia), MDAMB-435 (breast) and HCT-8 (colon). The good cytotoxicity for the three cancer cell lines

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.

A series of eleven (E)-2-benzothiazole hydrazones were synthesized and evaluated for their in vitro anticancer activities against three neoplastic cancer cells: HL-60 (leukemia), MDAMB-435 (breast) and HCT-8 (colon). Two of them, 3e and 3f, showed good cy

The amides and anilides of benzothiazol-2-ylthioacetic acid and 3-(benzothiazol-2-ylthio)propanoic acid were prepared by the reaction of the corresponding acid chlorides with amines and anilines.Also the arylhydrazones, the cycloalkanone hydrazones, and pyrazoline derivatives were prepared.
