Acyloxy radicals

Acyloxy radicals , including acyloxy radicals , are reactive intermediates in organic chemistry that are derived from diacyl peroxides (R = alkyl, aryl; specific example: diacetyl peroxide R = CH ₃ ). Acyloxy radicals are formed when diacyl peroxides are heated or photolysed . In radical polymerization - a leading technology in large-scale technology - for the production of plastics ( polyethylene , polystyrene , polyacrylonitrile , polyvinyl chloride , etc.), acyloxy radicals generated from diacyl peroxides play an important role in the initial reaction:

From subsequent reactions of the decomposition of acyloxy radicals, not only carbon dioxide but also esters and hydrocarbons can be formed through recombination of the radicals . The following reaction scheme shows the formation of the radicals R · by decarboxylation and the dimerization of R · to R – R:
