Abstract


3-Aryl-4-oxoalkane-1,1,2,2-tetracarbonitriles were synthesized by the interaction of 2-aryl ketones with tetracyanoethylene. Directed rearrangement of them in acetic acid in the presence of ammonium acetate led to the formation of 2-(3-cyano-5-hydroxy-1,5-dihydro-2H-pyrrol-2-ylidene)malononitriles containing an aryl substituent in conjugation with the acceptor buta-1,3-diene-1,1,3-tricarbonitrile moiety.
