    Iodo- and chlorodemercuration of 5,5′-mercuribisuracils (1985)
    Springer
    Chemistry of heterocyclic compounds 21 (1985), S. 322-325

    Notes: Abstract The direct C mercuration in the 5 position of 1-acetyluracil by means of mercury (II) trifluoroacetate in anhydrous acetonitrile is described. The intermediately formed 1-acetyl-5-trifluoroacetoxymercuriuracil, without isolation, was subjected to symmetrization by the action of potassium iodide. The acetyl groups were then readily split out by the action of water. The resulting 5,5′-mercuribisuracil (50% yield) forms 5-iodo- or a 5-chlorouracil in 93% or 72% yields, respectively, under the influence of an aqueous KI3 solution or excess pure liquid S2Cl2.

    Novel synthesis of 5-halouracils from 5-mercuri-2,4-dimethoxypyrimidines (1989)
    Springer
    Chemistry of heterocyclic compounds 25 (1989), S. 205-208 
    Details
    ISSN: 1573-8353
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Direct C-mercuration of 2,4-dimethoxypyrimidine with mercury (II) acetate has been shown to give the 5-mercuri-derivative, which is readily converted, either directly or via 5,5′ -mercuribis (2,4-dimethoxypyrimidine), into the 5-halo derivatives. Hydrolysis of the latter with hydrochloric acid affords the 5-halouracils.
