Various 2-aryl-3-arylazoacrylonitriles are synthesized while attempting the intramolecular N-arylation of 5-aminopyrazoles, using the hypervalent iodine reagent. The synthesis involves phenyl iodine diacetate-assisted ring opening of 5-aminopyrazoles at r

The reaction of 5-amino-1,3-diphenylpyrazole with benzaldehyde gives 5-benzylideneamino-1,3-diphenylpyrazole, wich then undergoes cyclization with mercaptoacetic acid to give 1,3,4-triphenyl-1H-pyrazolothiazepin-7-one.
