The Michael reaction of 1,3-dicarbonyls with α,β-unsaturated esters and nitriles has been carried out very efficiently, under mild and neutral conditions, in the presence of a catalytic amount of trans-hydrido(η1-O- enolato) ruthenium(II) complex (2), which is prepared from the reaction of Ru(cod)(cot) (1) (cod = cycloocta-1,5-diene; cot = cycloocta-1,3,5-triene) with dimethyl malonate in the presence of 1,2-bis(diphenylphosphino)ethane (dpe).
A simple, efficient and green procedure for Michael addition catalyzed by [C4dabco]OH ionic liquid

, p. 767 - 770 (2014/06/09)
A dabco-based basic ionic liquid, 1-butyl-4-aza-1-azaniabicyclo[2.2.2] octane hydroxide, has been developed as a catalyst for a convenient and rapid method for the Michael addition of active methylene compounds to α,β-unsaturated carboxylic esters and nitriles. The method is very simple, and the yields are very high. The catalyst can be recycled several times without much loss of activity.
