Abstract
The synthesis of a series of 12 β-dimethylaminovinylketones [RC(O)CH CHN(Me) 2 , where X = Ph, Me-4-Ph, F-4-Ph, Cl-4-Ph, Br-4-Ph, NO 2 -4-Ph, fur-2-yl, thien-2-yl, pirrol-2-yl, pyrid-2-yl, CH(OMe) 2 and hexyl] from the condensation reaction of methyl ketones with dimethylformamide dimethylacetal in the presence of equimolar amounts of imidazolium based ionic liquids [BMIM] · BF 4 and [OMIM] · BF 4 is reported. The reaction time and the yields were investigated and this method showed advantages over the methods described in the literature.
