The novel, highly versatile 2-(benzothiazol-2-yl)-1bromo-1,2-ethanedione-1-arylhydrazones 3 were prepared and their behavior toward some nucleophiles was investigated. Thus, reaction of 3 with the sodium salt of malononitrile afforded the aminopyrazolecarbonitriles 5 that undergo cyclocondensation w
