coupling (CDC) reaction for the formation of CC and CP bonds is disclosed using a catalyticamount of DDQ (10 mol %) underaerobicconditions (see scheme). This unprecedented environmentally benign strategy of using AIBN (10 mol %) and molecular oxygen to regenerate DDQ exhibits a larger substrate scope. For the first time, an efficient utility of 4‐hydroxycoumarins as pronucleophiles for CDC is presented
