ALDOL AND KNOEVENAGEL CONDENSATIONS CATALYZED BY MODIFIED MG-AL HYDROTALCITE - A SOLID BASE AS CATALYST USEFUL IN SYNTHETIC ORGANIC-CHEMISTRY

Aldol and Knoevenagel condensations were performed with suitably activ ated Mg-Al hydrotalcite as catalyst in quantitative yields in the liqu id phase under mild reaction conditions at a faster rate for the first time.
