The reaction of 6-trifluoromethanesulfonyloxy-4(3H)-pyrimidinones with Me₂Cu(CN)Li₂, anti with vinyl tributyltin, trimethylsilylacetylene, and zinc cyanide with palladium catalysis, are described for the synthesis of a variety of fully functionalized 6-substituted-4(3H)-pyrimidinones of interest as herbicides.
