Abstract We report the preparation and characterization of three pyrimidine-based monomers, specifically: 1-(2-diallylaminoethyl)uracil, 1-(2-diallylaminoethyl)thymine and 1-(2-diallylaminoethyl)cytosine. Monomer synthesis was initiated by reaction of the pyrimidine with ethylene carbonate to form the hydroxyethyl adduct which was subsequently chlorinated to afford the chloroethyl intermediate. Reaction of the chloroethyl derivatives with diallylamine resulted in the desired monomers. We demonstrated a two-fold increase in the overall yield of the three monomers in comparison to reported procedures. The cyclopolymerization and cyclo-copolymerization of 1-(2-diallylaminoethyl)pyrimidine trifluoroacetate salts in water resulted in low-yield homopolymers. In contrast, the neutral 1-(2-diallylaminoethyl)pyrimidines cyclo-copolymerized with sulfur dioxide and V-50 initiator to yield the corresponding copolymers in higher yields ranging from 30 to 60%.

1-(2-二烯丙基氨基乙基)嘧啶的合成与聚合

摘要 我们报告了三种基于嘧啶的单体的制备和表征，特别是：1-(2-二烯丙基氨基乙基)尿嘧啶、1-(2-二烯丙基氨基乙基)胸腺嘧啶和 1-(2-二烯丙基氨基乙基)胞嘧啶。通过嘧啶与碳酸亚乙酯反应形成羟乙基加合物，随后将其氯化以提供氯乙基中间体，从而引发单体合成。氯乙基衍生物与二烯丙胺的反应产生所需单体。与报道的程序相比，我们证明了三种单体的总产率增加了两倍。1-(2-二烯丙基氨基乙基)嘧啶三氟乙酸盐在水中的环聚合和环共聚合导致低产率均聚物。相比之下，
