We described herein the use of selenium compounds in Click Chemistry by copper catalyzed 1,3-dipolar cycloaddition of azidomethyl arylselenides with alkynes. The reactions were performed under mild conditions reacting azidomethyl arylselenides with a range of terminal alkynes using catalytic amount of Cu(OAc)2.H2O/sodium ascorbate and the corresponding 1-(arylseleno-methyl)-1,2,3-triazoles were obtained
我们在本文中描述了Click化学中硒化合物在铜与叠氮基之间的铜催化的叠氮甲基芳基硒化物的1,3-偶极环加成反应中的用途。反应在温和条件下进行,使用催化量的Cu(OAc)2 .H 2 O /抗坏血酸钠和相应的1-(芳基硒代甲基)-1,2,3-三唑使叠氮基甲基芳硒化物与一系列末端炔烃反应以高收率获得。使用微波辐射,这些反应的反应时间可以减少到几分钟。
