Electrochemical phosphorylation of arenes catalyzed by cobalt under oxidative and reductive conditions

Catalyst capable to operate in cathode and anode spaces simultaneously was found. Electrochemical regeneration of active form of catalyst Co2+bpy (1%) under oxidative as well as reductive conditions allows the C–H/P–H coupling of dialkyl-H-phosphonate and various aromatic or heteroaromatic compounds.
