A route to dicyanomethylene pyridines and substituted benzonitriles utilizing malononitrile dimer as a precursor
The conditions of the reaction of malononitrile dimer with enaminones and arylidenemalononitrile could be adapted to yield either pyridines or benzene derivatives. A new synthesis of pyrido[1,2-a]pyrimidines from the reaction of malononitrile dimer 1 and

Syntheses with Nitriles, LXXV. The Reactivity of the Dimers of Malononitrile and Cyanoacetate with Dimethylformamide-dimethylacetal
Reaction of malononitrile dimer (1) and the codimer from cyanoacetate and malononitrile (2) with dimethylformamide-dimethylacetal (DMFDMA) leads to the monocondensation products 5a, b.The isomeric codimer 3, however, gives the amidine 6.Ring closure react
