Notes:
Rate constants of various simultaneous reactions of t-butoxicarbonyl and t-butyl radicals generated by photolysis of t-butylpivalate in n-heptane are directly determined by kinetic electron spin resonance. The temperature dependence of the decarboxylation reaction t-BuOĊO → t-Bu. + CO2 obeys log )K/S-1( = 13.8-49.0/θ where θ = 2.303 RT/kJ . mol-1. The self- and cross-termination of the radicals are diffusion limited.
