THERMAL HETEROCYCLIZATION OF METHYL ARYL KETAZINES. REACTIONS OF THE TAUTOMERIC ENEHYDRAZINE FORM

Over the temperature range 220-280 deg C the thermal reactions of methyl aryl ketazines (Ar=C6H5-, 4-CH3C6H4-, 4-CH3OC6H4-, and α-naphthyl-) proceed with their cyclization to give pyrazoline and benzodiazepine derivatives.With an increase in temperature to 320-350 deg C the subsequent transformations of these compounds lead to the formation of substituted pyrazoles, 1-methyl-1,2-diarylcyclopropanes isomeric olefins, low-molecular-weight aromatic hydrocarbons, and isoquinolines.
