The radical telomerization of ethylene with 1,1-dialkoxyalkanes, initiated by tert-butyl peroxide (140-150 deg C), was investigated.The main products are unsymmetrical linear acetals, esters and saturated hydrocarbons.The structure of the intermediate free radicals was studied by ESR spectroscopy.The values obtained for the partial chain transfer constants (Cn=0.2) characterize the 1,1-dialkoxyalkanes as telogens of medium activity.The telomerization of ethylene with 1,1-dimethoxyethane is accompanied by rearrangements with 1,5 and 1,9 migration of a hydrogen atom.
