Displacement reactions of 5-chloro-4-phenylazopyrazoles

3-Methyl or 3-phenyl-5-chloro-1-phenyl-4-phenylazopyrazole with primary amines, sodium polysulfide and sodium azide yielded amines, disulfides and 2,4-dihydropyrazolo[3,4-d]-1,2,3-triazoles respectively. 4-Amino-5-anilino-1,3-diphenylpyrazole was also prepared and characterized.
