Three-component coupling reaction of terminal alkyne, sulfonyl azide, and amine for the synthesis of N-sulfonyl amidine was developed using heterogeneous [email protected] catalyst, which was generated by pyrolysis of HKUST-1 (Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylate). A variety of terminal alkynes, sulfonyl azides, and amines underwent three-component coupling in the presence of 5 mol % [email protected]
使用多相[受电子邮件保护的]催化剂开发了末端炔烃,磺酰基叠氮化物和胺的三组分偶联反应,用于合成N-磺酰基am,该催化剂是通过热裂解HKUST-1(Cu 3(BTC)2,BTC)生成的= 1,3,5-苯三羧酸酯)。在5 mol%的存在下,各种末端炔烃,磺酰叠氮化物和胺类进行了三组分偶联[电子邮件保护]所使用的[电子邮件保护]催化剂易于通过离心分离,可以重复使用至少3次而不会损失。反应性。过滤实验表明,已开发的[电子邮件保护]催化基本上是多相的。
