Reactions of fluoroalkyl radicals. Part 6.—Addition of fluoromethyl radicals to ethylene

Abstract

The addition of fluoromethyl radicals to ethylene in the gas phase has been studied over the temperature range 17–182°C, using the abstraction of a hydrogen atom from hydrogen sulphide as the competing reaction: [graphic omitted] Values of 0.91 ± 0.18 and –1.32 ± 0.29 kcal mole^–1 have been determined for log (A₂/A₁) and E₂—E₁ respectively. Fluoromethyl radicals add readily to ethylene, their reactivity being intermediate between those of methyl and trifluoromethyl.
