of a single alkene to radical-dual-difunctionalization of twodifferentalkenes! Abundant aliphatic aldehydes were readily decarbonylated into alkyl radicals for the cascade construction of C(sp3)–C(sp3), C(sp3)–C(sp3) and C(sp3)–O bonds via double radical addition and radical–radical coupling, following the intrinsic nucleophilic/electrophilic reactivity of both the radicals and alkenes.

A three-component reaction of alkenes, aldehydes, and hydroperoxides catalyzed by FeCl2 to beta-peroxy ketones has been achieved. This three-component reaction can be also applied to the synthesis of a-carbonyl epoxides, through either a stepwise base-induced epoxidation of the separated beta-peroxy ketone products or a one-pot process by simply adding base to the reaction mixture after the completion of the three-component reaction.
