Abstract

Abstract Free radical addition of propanal to double bonds, initiated by benzoyl peroxide, mainly leads to two adducts, an aldehyde and a ketone, when the double bond has a methylene group; these results are explained in terms of polar effects in the free radical transfert reactions. When the double bond has no methylene group, only the ketonic adduct is obtained; the steric effects in the free radical addition step explain these results.
