Abstract
Selective monolithiation of 2,5-dibromopyridine at either the 2-position or the 5-position is reported. Solvent and concentration strongly influence the selectivity. Coordinating solvents and higher concentration favor the 5-position while non-coordinating solvents and lower concentration favor the 2-position.
Keywords
