A facile one pot three component reaction of alkyl halides, sodium azide with terminal alkynes can be catalyzed by functionalized graphene oxide copper (I) complex under ultrasonic irradiation at room temperature. In this protocol, the 1,4-disubstituted 1,2,3-triazoles were afforded as target pure products in excellent yields and short reaction times. The prepared catalyst has been characterized by
在室温下超声辐射下,官能化的氧化石墨烯铜(I)配合物可催化烷基卤化物,叠氮化钠与末端炔烃的一锅三组分反应。在该方案中,以优异的产率和较短的反应时间提供了1,4-二取代的1,2,3-三唑作为目标纯产物。通过傅立叶变换红外光谱(FT-IR),X射线衍射光谱(XRD),能量分散X射线(EDX)和场发射扫描电子显微镜(FE-SEM)技术表征了所制备的催化剂。而且,该催化剂是化学选择性的和稳定的,并且可以重复使用几次,而其催化活性没有任何明显的损失。
