6-Alkyl-1,3-diakyl-5-fluorouracil (3a-3f) were synthesized by the reaction of the lithium derivative of 1,3-dialkyl-5-fluorouracil with methyl iodide or alkyl trifluoromethanesulfonate. We found that the methylated products were ethyl-substituted derivatives, not methyl-substituted derivatives. A possible mechanism is also proposed for the ethylation process.

cis-Oxidative adducts are isolated by the reaction of Pd(0) complexes or Pt (CH2=CH2 ) (PPh3)2 with 1,3-dialkyl-5-fluoro-6-iodouracils, and in palladium cases cis-adducts further isomerize to trans-ones in solution completely.
