Abstract

A three-component reaction of acetophenone, aromatic aldehydes, and aniline derivatives has been achieved in the presence of a ZnS@nitrogen graphene quantum dot (N-GQD) nanocomposite as a highly effective heterogeneous catalyst to produce β-amino carbonyls. The catalyst has been characterized by XRD, SEM, TEM, FT-IR spectroscopy, EDS, BET and TGA techniques. The feasibility of carrying out the one-pot synthesis under ultrasonic irradiation with a heterogeneous nanocatalyst could improve the reaction rates and shorten the reaction times.

摘要

在硫化锌@氮掺杂石墨烯量子点（N-GQD）纳米复合材料作为高效多相催化剂存在的条件下，实现了苯乙酮、芳香醛和苯胺衍生物的三组分反应，以制备β-氨基羰基化合物。该催化剂已通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、傅里叶变换红外光谱（FT-IR）、能谱分析（EDS）、比表面积分析（BET）和热重分析（TGA）技术进行了表征。使用多相纳米催化剂在超声辐射下进行一锅法合成的可行性可以提高反应速率并缩短反应时间。
