Abstract
The kinetics of rearrangement of -dichlorophenyl(1H-1,2,4-triazol-1-yl methyl)ketone enol acetate into phenyl(5-acetyl-1H-1,2,4-triazol-1-ylm ethyl)ketone were investigated by H-1 NMR spectroscopy. It was shown t hat this rearrangement is a first-order reaction. The rate constant wa s measured in the 129-156-degrees-C range and the activation parameter s of the reaction were determined. A hypothesis concerning the intramo lecular character of the observed rearrangement was drawn based on the kinetic data.
