Reaction between amine and aldehyde
WebKnoevenagel reaction is a condensation between an aldehyde or a ketone with an active hydrogen compound in the presence of a basic catalyst to yield α, β -unsaturated compounds. Usually the catalyst is a weakly basic amine, and the active hydrogen compound bears electron-withdrawing groups such as CO 2 R, COR, CHO, CN, or NO 2.

WebDec 10, 2024 · An amine is a compound derived from ammonia (NH 3 ); it has one, two, or all three of the hydrogen atoms of NH 3 replaced by an alkyl (or an aryl) group. Like NH 3, amines are weak bases. The functional group of an amine is a nitrogen atom with a lone pair of electrons and with one, two, or three alkyl or aryl groups attached.
