Free radical addition to olefins. Part 9.—Addition of methyl radicals to fluoro-ethylenes

Abstract

A method to determine the relative rate of addition of methyl radicals to each end of a series of fluoroethylenes has been developed and the following differences (Δ) in activation parameters determined. CH₃·+ RCHCH₂[graphic omitted]CH₃CH₂ĊHR [graphic omitted] These figures show considerably different trends to those observed for the addition of trichloromethyl and heptafluoropropyl radicals to the same olefins.
