The condensation of aryl methyl ketones 6 with acetic anhydride 4a in the presence of the boron trifluorideacetic acid adduct 7 gives rise to the formation of 4aryl-2,2-difluoro-6-methyl-1,3,2-(2H)-dioxaborines 8 in satisfactory yields. The stable 4-aryl-2,2-difluoro-6methyl-1,3,2-(2H)-dioxaborines
