Michael reaction acceptors are the functional groups in which the olefins or acetylenes conjugated to electron-withdrawing groups.

Michael reaction is a typical nucleophilic addition reaction, is always an organic chemistry domain research hot spot.

Studies on the Michael reaction have been carried out under ultrasound irradiation.

2-cyanoethyl-5-norbornene-2-carboxaldehyde was synthesized through a Michael addition reaction of acrylonitrile and 5-norbornene-2-carboxaldehyde using tert-butyl alcohol and potassium hydroxide as catalyst at room temperature.

A lower generation dendritic twelve ester has been synthesized from ethylenediamine and acrylic twelve ester by means of Michael addition reaction in the solvent of methanol .

In this paper,hyperbranched functional molecular skeleton terminated with ester and amido groups,with carbon chain length of 12 and 16 were synthesized by divergent method by means of C12 and C16 fatty amine as the core,and then separately with methyl acrylate and ethylenediamine alternating Michael addition reaction and amidation condensation reaction.

Six carboxyl acids DEMB was produced with Michael Reaction using triethylamine as alkaline catalyst and solvent, malonic acid and itaconic acid as raw materials.
