The first paired electrolysis-enabled arylation of quinoxalin-2(1H)-ones was achieved using cyanoarenes as the reagents. A variety 3-arylquinoxalin-2(1H)-ones with various important functional groups were obtained in moderate to good yields under metal- and chemical oxidant-free conditions. With a pair reductive oxidative processes occurring among substrates reaction intermediates, power consumption can be dramatically reduced.

Abstract Herein, we present a (NH 4 ) 2 S O 8 mediated difunctionalization reaction of aryl alkenes with quinoxalinones and P(O)SH compounds. This method enables the synthesis various phosphorothioate‐containing quinoxalin‐2(1 H )‐one derivatives (46 examples) in 37–79% yields. The is compatible range functional groups easily adaptable to large‐scale synthesis. Preliminary studies suggest involvement phosphorothioate radicals these transformations.

Visible-light photoredox-catalyzed method has been developed for the synthesis of quinoxalin-2(1H)-one-containing vinyl phosphorodithioates via direct difunctionalization alkynes with quinoxalin-2(1H)-ones, P4S10 and alcohols. This four-component reaction could be carried out under metal-free mild conditions, affording a number in moderate to good yields Z-isomers as major products. Photocatalytic radical mechanism is proposed based on results trapping fluorescence quenching experiments.
