Abstract
1. A study was made of the products of the reactions of the free 1-cyano-1-methylethyl radical with 1-heptene, α-methylstyrene, and isobutene and also of the gasoues products of the decomposition of 1-methyl-3-phenyltriazene in heptane, 1=heptane, and α-metyhlstyrene. 2. It was shown that the presence of ethylenic double bonds leads to substantial reduction in the contribution made by the reaction of removal of a hydrogen atom from a hydrocarbon molecule by a free radical and, in certain cases, to complete suppression of this reaction (e.g. in the reaction between free methyl and α-methylstyrene). 3. The main products of the reactions of the free 1-cyano-1-methylethyl radical with 1-heptene and with isobutene are compounds of the type R - A - A - R, in which A is the hydrocarbon molecule. With α-methylstyrene reaction is mainly in the direction of disproportionation of free radicals with formation of R - A.
