Kinetics and Mechanism of Initiated Oxidation of 4,7-Dihydro-1,3-dioxepines
摘要
Abstract
The initiated oxidation of 4,7-dihydro-1,3-dioxepine and 2-isopropyl-4,7-dihydro-1,3-dioxepine with molecular oxygen in the liquid phase (323 K) was studied. Microvolumetry, IR Fourier-transform spectroscopy, 1H NMR spectroscopy, potentiometry in combination with computer simulation and quantum chemical calculations were used. It was found that during the oxidation process, continuation of chains is realized due to the abstraction of a hydrogen atom by the peroxyl radical from the CH bond of the cycloolefin weakened by conjugation.
