REARRANGEMENT OF RADICALS IN THE HOMOLYTIC ADDITION OF m-XYLENE TO METHYL METHACRYLATE

Investigation of the products from the reaction of m-xylene with methyl methacrylate under the conditions of thermal and peroxide initiation led to the isolation and identification of compounds which indicated that rearrangement of the intermediate radical-adducts occured in addition to the main process.The rearrangement takes place mainly with 1,5-H migration, but 1,3-H migration also takes place at high temperatures (350 deg C).
