| 摘 要： | A novel rearrangement reaction about 2-benzothiazolylthioacetyl hydrazide (1) to produce s-triazolo[3,4-b] benzothiazol-3-thiol (3) in the presence of KOH and CS2 was described.Other way to synthesize 3 from 2-benzothiazolyl-hydrazine (2) under the same condition was compared and the Mannich reaction of compound 3 was reported too.Their structures were established by elemental analyses,IR,^1H nmr and MS spectra.
