Process for pyrimidinone compounds

This invention relates to a process for the preparation of pyrimidinone compounds of the formula STR1 wherein Ar is an optionally substituted aryl or heteroaromatic moiety, R3 is an optionally substituted alkyl, alkenyl or alkynyl, R5/sup

6-Trifluoromethanesulfonyloxy-4(3H)-pyrimidinones as veratile intermediates for the synthesis of 6-functionalised 4(3H)-pyrimidinones

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.
