Ammonium chloride catalyzed Knoevenagel condensation in PEG-400 as ecofriendly solvent

Waghmare, Smita R.

, p. 849 - 855 (2021/09/28)

A simple and selective green methodology has been successfully developed for Knoevenagel condensation in polyethylene glycol-400 using 10 mol % ammonium chloride as catalyst. The method is applicable to a wide range of aromatic, heteroaromatic and α,β-unsaturated aldehydes. The reactions have been found to be clean and free from the formation of the Michael adduct.
