autoxidation of aliphatic aldehydes are investigated. Decarbonylation of acyl radicals proceeds smoothly when the alkyl radicals that are formed can be stabilized by allylic conjugation. Further conjugation of the double bond in the allyl radical with a carbonyl or a cyclopropyl group allows position-selective peroxidation of the alkyl radical.
