An efficient transition-metal-free synthetic method of 1H-indazoles has been developed. The reaction of arylhydrazones in the presence of montmorillonite K-10 in 1,2-dichlorobenzene at 130 °C afforded 1H-indazoles in good yields most likely via a sequenti

An efficient [bis-(trifluoroacetoxy)iodo]benzene (PIFA)-mediated oxidative C-N bond formation is developed for the synthesis of 1H-indazoles from readily available arylhydrazones. The reaction tolerates a wide range of functional groups and has broad scope of substrates. Moreover, this method is a relative green and reliable method for rapid preparation of substituted 1H-indazoles under mild conditions.
