Abstract :

The objective of the present study is to provide Cs–MCM–41 as catalyst for the Knoevengel condensation of salicylaldehyde with ethyl cynoacetate. Cesium was dopped in MCM–41 via ion exchange method and the catalytic performances of the samples were investigated for an efficient, high–yielding, one–pot synthesis of 3–cynocoumarine. The influence of cesium loading on the basic properties of MCM–41 was also studied.
