Electrochemical Functionalization of Alkenes with 1,3-Dicarbonyl Compounds via Radical Addition

Herein, an electrochemical approach for the functionalization
of
alkenes with 1,3-dicarbonyl compounds under oxidative conditions is
reported. 1,3-Dicarbonyl compounds undergo single-electron transfer
(SET) to generate electrophilic radicals, which upon addition to styrene
and aliphatic alkenes afford the 1,2-bifunctionalized and α-alkylated
products, respectively. The methodology avoids the usage of external
oxidants and shows good tolerance with respect to alkene derivatives.
