The paper deals with the synthesis of 4-(2-furyl)- and 4-(2-thienyl)pyrimidines, their quaternization reactions with 2-bromoacetophenones, 2-bromoacetonaphthone and ethyl bromoacetate and the obtaining of 4-(2-furyl)- and 4-(2-thienyl)pyrimidinium ylides, by treating the corresponding quaternary salts with bases. The dipyrimidino-pyrazinic dimmers were obtained as inactivation products of 4-(2-furyl)- and 4-(2-thienyl)pyrimidinium ylides.
