Abstract

Detailed mechanisms have been proposed and confirmed for the interaction of the ethyl radical with allyl ethyl ether vapour (between 49 and 147°) and with diallyl ether vapour (between 63 and 153°). Arrhenius parameters have been measured for all the significant reactions of metathesis, addition and dismutation in these systems, and the results are discussed in relation to the structural characteristics of the ethers. Good yields of ethoxyl and allyl radicals may be obtained from the allyl ethyl ether and diallyl ether systems respectively, and the latter also yields allyloxyl radicals in significant quantity. The patterns of interaction of the ethyl radical with the ethoxyl radical and with the allyl radical have been studied over a range of temperature, and the results are consistent with the general equation governing the interaction of alkyl radicals.
