heterogeneous catalyst for the Mannich reaction. One-pot multi-component condensation of an aldehyde, an amine and a ketone at ambient temperature affords the corresponding β-amino ketones using novel nano-sized Rb2HPW12O40. Simple purification, short reaction time and high yield are some of the advantages of this reaction. Also, the catalyst can be readily isolated. The nano catalyst Rb2HPW12O40 has
所描述的研究目的是研究Rb2HPW12O40作为曼尼希反应的绿色多相
催化剂。使用新型纳米级Rb2HPW12O40,在环境温度下通过一锅法将醛,胺和
酮进行多组分缩合,可得到相应的β-
氨基
酮。简单纯化,短反应时间和高产率是该反应的一些优点。而且,
催化剂可以容易地分离。通过傅里叶变换红外光谱,X射线粉末衍射和扫描电子显微镜对纳米
