Interestingly, direct nitration of 2-fluoro and 2,6-difluoropyridine with nitronium tetrafluoroborate achieved a degree of success and whilst 2-fluoropyridine gave mostly the N-nitro salt, a 6% yield of 5-nitro-2-fluoropyridine was obtained and 2,6-difluoropyridine gave a 20% yield of 3-nitro-2,6-difluoropyridine. |
