gave (E)-5-(2-carboxyvinyl)uracil which, upon reaction with the appropriate N-halogenosuccinimide, gave (E)-5-(2-bromovinyl)uracil, (E)-5-(2-chlorovinyl)uracil, and (E)-5-(2-iodovinyl)uracil. The last mentioned compound was also obtained by the action of iodine chloride on 5-vinyluracil. 5-(1-Chlorovinyl)uracil upon treatment with bromine gave 5(2-bromo-1-chlorovinyl)uracil which reacted with sodium
