The kinetics of the Fischer thermal indolization of monosubstituted cyclohexanone arylhydrazones was studied by the spectrophotometric method.The enthalpy and entropy of activation of the reaction were calculated.The data obtained were interpreted in terms of a consistent mechanism of formation of a carbon-carbon bond (the <3,3>-sigmatropic shift).It was found that the influence of the electronic factors on the rate of the sigmatropic rearrangement is inappreciable.
