摘要：

The synthesis of a series of 12 beta-dimethylaminovinylketones [RC(O)CH=CHN(Me)(2), where X = Ph, Me-4-Ph, F-4-Ph, CI-4-Ph, Br4-Ph, NO2-4-Ph, fur-2-yl, thien-2-yl, pirrol-2-yl, pyrid-2-yl, CH(OMe)(2) and hexyl] from the condensation reaction of methyll ketones with dimethylformamide dimethylacetal in the presence of equimolar amounts of imidazolium based ionic liquids [BMIM] . BF4 and [OMIM] . BF4 is reported. The reaction time and the yields were investigated and this method showed advantages over the methods described in the literature. (C) 2007 Elsevier B.V.
