The Knoevenagel Condensation in Water

Current Organic Synthesis, 2012
The Knoevenagel condensation is an important C-C bond forming reaction which has been extensively studied and also applied in industrial processes. Although it involves a dehydration step, the reaction can be successfully carried out in water to produce electron deficient alkenes and heterocyclic compounds such as coumarins.

Catalysis of the knoevenagel condensation

Tetrahedron Letters, 1985
Abstract Xonotlite alone or made more basic by doping of potassium t -butoxide catalyses the title reaction between aromatic aldehydes and malononitrile or alkyl cyanoacetates. At ambient temperatures, this procedure specifically gives high yields of E olefinic Knoevenagel products.
