Abstract

Abstract: Absolute rate expressions for the abstraction of hydrogen from thiophenol in nonane by tert-butyl, isopropyl, n-butyl, and n-octyl radicals were determined by kinetic absorption spectroscopy (KAS). Alkyl radicals were produced by photolysis of dialkyl disulfides or by photolysis of mixtures of di-tert-butyl peroxide and trialkylphosphine in the presence of thiophenol. Arrhenium expressions for alkyl radicals from the phosphine ...
