An organoelectrophotocatalytic approach for the C−H silylation of heteroarenes through dehydrogenation crosscoupling with H 2 evolution has been developed. The organoelectrophotocatalytic strategy is carried out under a simple and efficient monocatalytic system by employing 9,10-phenanthrenequinone both as an organocatalyst and as a hydrogen atom transfer (HAT) reagent, which avoids the need for an external HAT reagent, an oxidant, or a metal reagent. A variety of heteroarenes can be compatible in satisfactory yields with excellent regioselectivity.

Electrochemistry employs electrons as reagents and avoids the use of traditional redox reagents, which becomes a powerful tool in oxidative dehydrogenation cross-coupling reactions. 1,3-Dicarbonyl derivatives are common and easily available...

An organophotoelectrochemical approach for the silylation cyclization of CF3-substituted N-arylacrylamides with organosilanes has been developed. This photoelectrochemical method uses 9,10-phenanthrenequinone (PQ) as both a catalyst and a hydrogen atom transfer...
