Rates of reaction of allyl radicals: A reassessment

Abstract

Abstract Values of the rate constants for allyl‐radical abstraction from toluene and allyl‐radical recombination have been recalculated in the light of recent data on butene‐1 decomposition. The rate of recombination is in good agreement with that found by Van den Bergh and Callear [13] and the cross‐combination ratio for the allyl + methyl system has a “normal” value of almost 4. It is concluded that allyl radicals behave like alkyl radicals in respect of their rates of reaction with other radicals.
