Abstract

A facile Michael addition of ferrocenylenones with aliphatic amines under ultrasound irradiation in the absence of solvent and catalyst at room temperature can afford 1-ferrocenyl- 3-amino carbonyl compounds rapidly in high yields, which is also efficient in the aza- Michael reaction of other α, β-unsaturated carbonyl compounds such as chalcone, carboxylic ester, etc. However, aromatic amines do not undergo the conjugate addition at ...
