(Cu, Fe, Mn, Co) catalyzed peroxidation of β-dicarbonyl compounds at the α position by tert-butyl hydroperoxide was discovered. A selective, experimentally convenient, and gram-scale method was developed for the synthesis of α-peroxidated derivatives of β-diketones, β-keto esters, and diethyl malonate. Virtually stoichiometric (2−3/1) molar ratios of tert-butyl hydroperoxide and a dicarbonyl compound
