ABSTRACT
A synthesis of 1,4-benzothiazine, 1,4-benzoxazine, 1,4-quinoxaline, imidazo[1,2-a] pyridine, imidazol [1,2-a] pyrimidine and pyrazole derivatives was accomplished from the reaction of hydrazonoyl bromide I with 2-aminothiophenol, 2-aminophenol, 1,2-phenylenediamine, 2- aminopyridine, 2-aminopyrimidine and some active methylene. Also, compound 1 reacted with some dipolorophile to give pyrazolines and pyrrolidino [3,4-c] pyrazolines. All structures were elucidated on the basis of elemental analyses and spectral data
