EXCHANGE REACTIONS CARBOXY RADICALS.
Abstract
The article briefly summarizes the problems centered around the detailed mechanisms of the decompositions of peroxide molecules. The methods of study included secondary deuterium kinetic isotope effects. Further study of these isotope effects on the decomposition of acetyl peroxide and the decarbosylation of the acetoxy radical intermediate were also carried out. The results indicated that the isotope effect on the decarbosylation of the acetoxy radical was 1.03 per deuterium. The isotope effect on the overall destruction of this peroxide was also found to be viscosity sensitive (1.03 in isooctane and 1.05 in nujol). These values are consistent with an overall picture for the reaction which allows for reversible acetoxy radical formation with diffusive separation and decarboxylation competing in the forward direction.
