Site-selective sequential coupling reactions controlled by “Electrochemical Reaction Site Switching”: a straightforward approach to 1,4-bis(diaryl)buta-1,3-diynes
Selectivity of aryl iodo over ethynyl iodo toward the Suzuki cross couplingreaction is explored by utilizing a palladium complex of amino‐etherheteroditopicmacrobicycle. Subsequently, unreacted ethynyl iodide undergoes homocoupling reaction in the same catalytic atmosphere, thereby representing a cascadedualC−Ccouplingreaction. Furthermore, this approach is extended for novel one‐pot synthesis
