The Michael addition reaction of α , β ‐unsaturated ketones with malononitrile catalyzed by KF‐montmorillonite was investigated. It was interesting to note that at different reaction temperatures the addition and cycloaddition reaction products were obtained. This method has the advantages of good yields, mild reaction conditions, easy work‐up and inexpensive reagents over the existing procedures.
