Mechanisms of Thermal Isomerization of ortho-, meta-, and para-Difluorobenzene Isomers
摘要
Abstract
The mechanism of the thermal isomerization reactions of ortho-, meta-, and para-difluorobenzenes was established by DFT/B3LYP/6-31G (d) calculations. It was shown the rate-limiting step of these processes involve the dearomatization of difluorobenzenes to form benzvalene intermediates.
