Selectivity of aryl iodo over ethynyl iodo toward the Suzuki cross coupling reaction is explored by utilizing a palladium complex of amino‐ether heteroditopic macrobicycle. Subsequently, unreacted ethynyl iodide undergoes homocoupling reaction in the same catalytic atmosphere, thereby representing a cascade dual C−C coupling reaction. Furthermore, this approach is extended for novel one‐pot synthesis
利用氨基-醚异双位大环钯的钯配合物,探索了芳基碘对乙炔碘对Suzuki交叉偶联反应的选择性。随后,未反应的乙炔基碘化物在相同的催化气氛中进行均偶联反应,从而代表级联双CC偶联反应。此外,该方法扩展到了不对称1,3-二炔的新型一锅法合成。
