Michael Addition


Recent Literature


An efficient cobalt-catalyzed reductive coupling reaction of alkyl halides with alkenes bearing electron-withdrawing groups in the presence of water and zinc powder in acetonitrile gave the corresponding Michael-type addition products in high yields. The mechanism is discussed.

The ionic liquid [bmIm]OH is a catalyst and a reaction medium for Michael additions. Although the addition to α,β-unsaturated ketones gives the monoaddition products, this ionic liquid always drives the reaction of open-chain 1,3-dicarbonyl compounds with α,β-unsaturated esters and nitriles toward bis-addition.
