Abstract

Simple and Solvent Free Knoevenagel Condensationby Using Gadolinium Oxide Catalyst

A simple solvent free reaction between aromatic aldehydes and active methylene compounds in pres-ence of gadolinium oxide as a catalyst at room temperature has been described. The reaction was carried by simple grinding method with good yield. The catalyst was recovered by filtration and can be reused. All the synthesized compounds were characterized by spectral and analytical methods byIR, 1H and 13C NMR.
