The coupling reaction of o-iodobenzoic acid with terminal alkynes by using a catalyst system of 10% Pd/C-Et3N-CuI-PPh3 has been studied in a variety of solvents. 3-Substituted isocoumarins were formed in good yields and with good regioselectivity when the reaction was performed in EtOH.
使用10% Pd/C - 三乙胺 - 碘化亚铜 - 三苯基膦催化剂体系，研究了邻碘苯甲酸与末端炔烃在多种溶剂中的偶联反应。当反应在乙醇中进行时，以良好的产率和区域选择性生成了3 - 取代异香豆素。
