An efficient one-pot synthesis of 1,2,3-triazoles via the three-component coupling reaction between benzyl or alkyl bromides, terminal alkynes, and sodium azide in the presence of catalytic amounts of Cu(OAc)2/MCM-41 catalyst has been described. This catalyst showed high catalytic activity and 1,4-regioselectivity for the [3 + 2]Huisgen cycloaddition. This method avoids isolation and handling of organic
在催化量的 Cu(OAc)2/MCM-41 催化剂存在下,通过苄基或烷基溴、末端炔烃和叠氮化钠之间的三组分偶联反应,高效一锅法合成 1,2,3-三唑已经描述。该催化剂对[3+2]Huisgen环加成反应显示出高催化活性和1,4-区域选择性。这种方法避免了有机叠氮化物的分离和处理,使用水作为溶剂,催化剂回收使这种合成成为真正的绿色过程。© 2012 Wiley Periodicals, Inc. 杂原子化学 23:415–421, 2012; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.21031
