Diverse dithioic acid copper complexes exhibit a high catalytic activity in the copper-catalyzed alkyne–azide cycloaddition using several solvents under different temperatures, showing a high efficiency with only 0.005 mmol catalyst/mmol alkyne or less. A dithioic acid copper complex derived from acetophenone was selected and used as the catalyst in the preparation of a library of 1,4-disubstituted-1
多种二硫酸铜配合物在不同温度下使用多种溶剂在铜催化的炔-叠氮化物环加成反应中表现出高催化活性,仅在 0.005 mmol 催化剂/mmol 炔烃或更少时表现出高效率。选择衍生自苯乙酮的二硫酸铜络合物作为催化剂制备 1,4-二取代-1,2,3-三唑库。该过程以高产率和良好的官能团耐受性发生。
