JOC., 53, 2740 (1998): A useful precursor to a large range of 2,3-disubstituted pyridines. Fluorine is activated to nucleophilic displacement & C-3 metallation is possible.
• The possibility of metallation at C-3, together with the ready nucleophilic displacement of the activated fluorine makes 2-fluoropyridine a useful precursor of a wide range of 2,3-disubstituted pyridines. See, e.g.: J. Org. Chem., 53, 2740 (1988):
