摘要
The Michael reaction of 1,3-dicarbonyls with alpha,beta-unsaturated esters and nitriles has been carried our very efficiently, under mild and neutral conditions, in the presence of a catalytic amount of trans-hydrido(eta(1)-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).
