oxidation of Fischer tungsten–carbene uracil complexes has been carried out. Several commonly used oxidants gave results strongly influenced by the presence of substituent on nitrogen atoms. In particular, usual oxidants failed in the oxidation of 3-alkyl uracil carbene complexes. Finally, we showed that t-butyl hydroperoxide is able to oxidize successfully also 3-alkyl uracil carbene complexes and can be used

A palladium catalyzed regioselective synthesis of 6-aryl uracils via oxidative Heckreaction (C–H bond functionalization) of uracils and arylboronic acids is reported. The method is simple, atom-economical, and high yielding.
