Thermal decomposition of N-substituted hepta(methoxycarbonyl)-3a,7a- dihydroindazoles proceeds through the elimination of hexamethyl benzenehexacarboxylate and results in the generation of l-aryl-3- methoxycarbonylnitrile imines, which are intercepted by both the electron-withdrawing and electron-releasing olefins, for example, methyl acrylate, cyclopentene, vinylcyclopropane, or ethyl vinyl ether, to form the corresponding pyrazolines and pyrazoles. In the presence of propan-2-ol, the main process proceeds through the addition of nitrile inline to the O-H bond to form methyl 2-isopropoxy-2-[2-(4-methoxyphenyl)hydrazono]acetate.
