Abstract

Abstract: Rate constants and Arrhenius parameters have been measured for the reactions of tert-butoxyl radicals with alkenes by using laser flash photolysis in benzene-di-tert-butyl peroxide (1: 2 v/v) as solvent. With norbornene and norbornadiene, additions to the double bonds were the only modes of reaction, whereas with cyclopentene and cyclopentadiene, hydrogen abstraction was a competitive process. The measured activation energies were ...
