<p>The disclosure relates to 2,6-dihalo-5-alkoxy-4-substituted pyrimidine compounds wherein X1 is a halogen, Q is a C1–C2 alkoxy and R1 is selected from vinyl, aryl, alkenyl, furanyl, and carbaldehyde (abstract figure). The disclosure also relates to methods of forming them and methods of using them to form herbicides, such as alky16-amino-2-halo-5-alkoxy-pyrimidine-4-carboxylate. Example reactions include organometallic halide reactions and organolithiations reactions. Example compounds include: 2,6-dichloro-5-methoxy-pyrimidine-4-carbaldehyde 2,6-dichloro-5-methoxy-4-furan-2-yl pyrimidine 2,6-dichloro-5-methoxy-4-allyl pyrimidine 2,6-dichloro-5-methoxy-4-vinyl pyrimidine</p> |
