A clean and simple synthesis of one-donor poly-acceptors systems containing 2,6-dicyanoamine moiety was accomplished via the reaction of 1-arylethylidenemalonodinitriles with arylidenemalonodinitriles in aqueous media catalyzed by TEBAC in the presence of K 2 CO 3 . The important intermediates were obtained successfully to confirm the mechanism in the absence of base under the same...
Three series of N-arylquinoline derivatives were synthesized by the three-component reactions of arylaldehyde, 3-arylamino-5,5-dimethylcyclohex-2-enone, and active methylene compounds including malononitrile, meldrum's acid, and 1,3-indenedione in ionic liquid [bmim + ][BF 4− ] at 90°C.
