The absolute rate constants for the reaction of some carbon-centered radicals with α-toluenesulfonyl chloride have been measured in solution by using laser flash photolysis techniques.At 298 K, the rate constants are 1.3*106, 1.2*106, and 1.0*108 M-1s-1 for n-butyl, sec-butyl, and phenyl radicals respectively.Arrhenius parameters were determined for n-butyl and sec-butyl radicals.Evidence that suggests the involvement of charge-transfer interactions is presented.Such rate-enhancing interactions have been shown to have a greater influence on the preexponential factor than on the activation energy.
