Title
A new silica based substituted piperidine derivative catalyzed expeditious room temperature synthesis of homo and hetero bis-Knoevenagel condensation products
Abstract

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 bis-Knoevenagel condensation products by our designed catalyst.
