从廉价和直接的起始材料设计新的非均相催化剂,以实现良性、温和的有机转化,现在在学术界和工业界都变得越来越重要。本研究探索了简单的超声辅助合成具有多孔结构的Al掺杂gC 3 N 4纳米片(Al@gC 3 N 4)以制备含金属的氮化碳。使用 FTIR、EDX 和 SEM 光谱对所得纳米复合材料进行表征,并通过形态结构和化学成分进行分析。gC 3 N 4表面AlCl 3的金属掺杂导致独特的纳米复合结构,结果是生产用于曼尼希反应的高效催化剂。反应在最佳时间以相对较高的平均效率高效进行,并通过简单的方法完成。此外,Al@gC 3 N 4易于回收利用,5次运行后催化性能无明显下降。

Inorganic-organic hybrid material catalyzed one-pot three-component Mannich reaction of ketones with aromatic aldehydes and different amines at ambient temperatures afforded beta-amino carbonyl compounds in excellent yields. This method provides a novel and improved modification of three-component Mannich reaction in terms of mild reaction conditions and clean reaction profiles, using small amount of catalyst, simple workup procedure and ease of recovery and reusability of catalyst.
