Abstract

Striking changes occur when the reactions of t-alkyl peroxides with aralkanals art: carried out at 100'. Carbonyl-containing products are formed indicating that the reactions of intermediate rtral kanoyl radicals become more important at the lower temperature. For example, the reaction of t-amyl peroxide with 4methyl-4 phenylpentanal (VI) at 100" gives 18% 4, 4-dimethyl-l-tetralone (VIII) and 18% 4methylvalerophenone (IX) and only 30% of ...
