A new silica based piperidine derivative has been designed, synthesized and characterized by solid state carbon 13 CP MAS NMR, BET surface area analysis, IR, TGA studies, elemental analysis and pH experiment. This has been efficiently utilized as a recyclable catalyst for both homo and hetero bis-Knoevenagel condensation products in aqueous-ethanol. This is the first report of the synthesis of hetero
通过固态碳13 CP MAS NMR,BET表面积分析,IR,TGA研究,元素分析和pH实验,设计,合成和表征了一种新的基于二氧化硅的哌啶衍生物。它已被有效地用作乙醇水溶液中均双和杂双-Knoevenagel缩合产物的可回收催化剂。这是我们设计的催化剂合成杂双-Knoevenagel缩合产物的第一份报告。
