become a useful tool for quickly increasing molecular complexity in synthesis. In this work, a three-component oxidative coupling of aryl aldehydes with α,β-unsaturated esters and tert-butyl hydroperoxide catalyzed by dirhodium(II) catalyst Rh2(esp)2 (esp = α,α,α′,α′-tetramethyl-1,3-benzenedipropanoate) under mild conditions is developed. The synthesized carbonylation peroxidation products (β-peroxyketones)

A general and practical method for the synthesis of α-ester–β-keto peroxides has been achieved by iron-catalyzed three-component reactions of alkenes, aldehydes, and TBHP. A wide variety of functionalized organic peroxides were synthesized efficiently and selectively.
