Özet:

 

Nitrile imines generated by the oxidative dehydrogenation   of aromatic aldehyde phenylhydrazones with chloramine-T as a catalytic   dehydrogenating agent were trapped in situ by 4-methoxy cinnamonitrile to   afford 3,4-diaryl-1-phenyl-4,5-dihydro-1H-pyrazole-5-carbonitrile in moderate   to good yields. The structures of the cycloadducts were confirmed by   spectral studies and elemental analysis.
