Reactions of methyl radicals with triethylborane in the gas phase

Abstract

The homolytic substitution at boron and hydrogen-abstraction reactions of methyl radicals with triethylborane have been studied in the gas phase: the values of log (k/ml mol^–1s^–1) are respectively 10·60 – 5200/4·58 T and 12·38 – 7780/4·58 T. A mechanism for propene production in reaction systems in which triethylborane and methyl radicals are present, and an estimate for the rate of homolytic substitution at boron by tertiary butoxyl radicals, are also given.
