Zinc acetate was used as the catalyst for Knoevenagel condensation of aromatic aldehydes with active methylene compounds in the absence of solvent at room temperature. The reactions proceed smoothly with the yields high up to 100%. The work-up procedure is very simple and the products do not require further purification.

Key words: Knoevenagel condensation, catalysis, zinc acetate
