Reductive debromination and coupling reaction in the thermolysis of 5-bromouracils in N,N-dialkylamides. Cleavage of the C(5)–bromine bond by an initial electron-transfer process
Thermolysis of various 5-bromouracils (1) in N,N-dialkylamides results in the formation of methylenebisuracils (2) and reductive debrominated products (3)via cleavage of the C(5)–Br bond; the latter involves a one-electron transfer process. The product distribution between (2) and (3) depends upon the nature of substituents in the uracil ring.

A simple synthesis of di(uracilyl)aryl methanes and 1,ω-bis[di(uracilyl)methyl]benzenes
Di(uracilyl)aryl methanes and their homologues, 1, omega-bis[di(uracilyl) methyl]benzenes, have been synthesized in good yields through the HBr-acetic acid catalyzed condensation of 1-alkyl-/1,3-dialkyluracil derivatives with readily available aryl aldehydes and dialdehydes.
