Abstract: Basic cesium-beta (Cs-beta) zeolite has been synthesized. It proved to be an effective catalyst in reactions of a number of α,β-unsaturated carbonyl compounds with malononitrile. It is shown that the process is either the Michael or Knoevenagel reaction, or tandem transformations generally initiated by the Michael reaction, which depends on steric hindrance at the carbonyl group and the β-position of the carboncarbon (CC) double bond adjacent to the carbonyl group. We have synthesized basic Cs-beta zeolite and showed that this is an effective catalyst for reactions of a number of terpenoid α,β-unsaturated carbonyl compounds with malononitrile leading to products of either Michael or Knoevenagel reactions or both.
