The development of straightforward and environmentally friendly techniques for synthesizing organophosphorus compounds with C(sp2)—P bonds would be of great value for the advancement of synthetic chemistry. An electrochemically driven dienylation strategy of arylphosphine oxides with allenylsilanes is reported for the efficient synthesis of dienyl phosphorus compounds. A wide range of dienyl organophosphorus compounds with various functional group tolerance were facilely obtained in moderate to great yield. Mechanistic studies indicate that the desired C(sp2)—P bond is constructed through the radical addition process between the phosphoryl radical and the allene carbon.

Key words: electrochemical, dienylation, phosphoryl radical, C(sp2)—P bond
