The cationic telomerization of tri- and tetramethylethylenes with allyl chlorides was studied.It was found that the reaction of tetramethylethylene with secondary and tertiary chlorides leads mainly to the formation of the side products on account of steric hindrances.During the cotelomerization of the initial telogens and taxogens their relative reactivities and the steric constants for the addition of the secondary chlorides to tetramethylethylene (s = 0.47) were determined.It was shown that during the formation of products with several tri- and tetrasubstituted carbon atoms the steric hindrances during the reaction of the reagents increase, and this leads to a decrease in the addition rate and to an increase in the amount of products from the side reactions.

The composition of the products from the cationic telomerization of 2-methyl-2-butene and 1-chloro-3-methyl-2-butene with halogen derivatives having various activities was studied.It was established that the telomerization of isoalkenes is accompanied by the secondary reaction of redistribution of the hydrogen halide from the products to the initial alkene.This reaction is determined mainly by the reactivity of the telogen and by the chemical nature of the alkene.
