A series of new 4,4 -(1,4-phenylene)dipyrimidines 5a-c, 8a-c, and 10a,b have been synthesized from the reaction of amidines 1a-c with the dienaminone 2, bis-chalcone 6, or ylidenemalononitrile 9. The reaction of malononitrile and ethyl cyanoacetate with 2 gave 6,6 -(1,4-phenylene)di(pyridin-2(1H)-on
