title: A new strategy for the synthesis of poly-substituted 3-H, 3-fluoro, or 3-trifluoromethyl pyridines via the tandem C-F bond cleavage protocol.
abstract: A new strategy for the synthesis of poly-substituted 3-H, 3-F, and 3-trifluoromethyl pyridines based on C-F bond breaking of the anionically activated fluoroalkyl group is described. A series of 2,6-disubstituted 4-amino pyridines were prepared through this domino process in high yields under noble metal-free conditions, making this method a supplement to pyridine synthesis.
