Boruah, Anima,Baruah, Mukulesh,Prajapati, Dipak,Sandhu, Jagir S.
, p. 653 - 658 (1998)
Cerium chloride heptahydrate proves to be an efficient catalyst for Michael addition of 1,3-dicarbonyl compounds, through a simple solvent free reaction under microwave irradiations.
Phase-transfer catalyzed Michael addition reaction using a new C 2-symmetric quaternary ammonium salt derived from l-proline
Su, Ce,Xie, Yi-Ming,Zhang, Qing-Tang
, p. 1004 - 1008 (2011)
A new C2-symmetric quaternary ammonium salt easily prepared from l-proline, was developed and used as an efficient phase-transfer catalyst (PTC) in Michael addition reaction of various active methylene compounds to aromatic enones. Malonate est
Dual catalysis of the Michael reaction
Laszlo,Montaufier,Lalatiana Randriamahefa
, p. 4867 - 4870 (1990)
The Michael reaction, with conjugate bases of β-diketones as donors and with α,β-unsaturated ketones as acceptors, is efficiently catalyzed by a combination of clay-supported nickel bromide (heterogeneous) and ferric chloride (homogeneous).
Ba(OH)2 AS CATALYST IN ORGANIC REACTIONS-PART XVI-CONTRIBUTION TO THE STUDY OF THE MICHAEL ADDITION MECHANISM TO CHALCONE IN INTERFACIAL SOLID-LIQUID CONDITIONS
Iglesias, M.,Marinas, J.M.,Sinisterra, J.V.
, p. 2335 - 2342 (1987)
The Michael addition of several active methylene compounds to chalcone, catalyzed in interfacial solid-liquid conditions is described.The mechanism of the process is analyzed using the Michael addition of diethyl malonate to chalcone as the reaction test.

Adib, Mehdi,Rajai-Daryasarei, Saideh,Pashazadeh, Rahim,Jahani, Mehdi,Amanlou, Massoud
, p. 1583 - 1588 (2018/06/11)
A simple and atom-economic synthesis of highly substituted thiophenes is demonstrated. Heating a solution of a chalcone and a linear/cyclic 1,3-dicarbonyl compound with elemental sulfur in CH 3 CN in the presence of NEt 3 at 80 °C af
Synthesis of biphenyl-based ligand: Application in copper-mediated chemoselective michael reaction
Sundar, M. Shyam,Bedekar, Ashutosh V.
, p. 3582 - 3593 (2015/08/11)
A biphenyl-based ligand attached was synthesized and screened in copper-mediated Michael reaction. The catalyst system works well with carbon or sulfur nucleophiles as Michael donors and cyclohexenone or chalcones as the acceptors under mild and neutral r
