Abstract

The kinetics of radical decomposition of di(ferr-butyl) trioxide was studied by spectrophotometry from the consumption of an acceptor of free radicals, 2,6-di(tert-butyl)-4-methylphenol, in CFCl3 and CH2Cl2 (in the latter case, in the presence of 0.1 M ButOOH). The activation parameters of the reaction (log(A/s-1) = 14.8±1.2 and 14.1±1.6, Ea = 21.6±1.4 and 20.1±1.9 kcal mol-1 in CFCl3 and CH2Cl2, respectively) and the probability of radical escape to the bulk (e = 0.9±0.1) were determined. The known experimental and calculated values of the O-OO bond strength in trioxides were analyzed.
