Polar effects in free-radical reactions. A new type of homolytic aromatic alkylation by silver catalyzed oxidation of acetone by peroxydisulphate in the presence of olefins.
Silver catalyzed peroxydisulphate oxidation of acetone in the presence of olefins and protonated heteroaromatic bases leads to compound I via addition of acetonyl radical to the olefin and scavenging of the resulting radical adduct by the aromatic base.
