摘要

Abstract Metal—halogen exchange between 2, 6-diiodo-and 2, 6-dibromopyridine and two equivalents of n-butyllithium gives 2, 6-dilithiopyridine. On quenching with either carbon dioxide followed by esterification, methanol or dimethyl disulfide the dilithio compound gives a methyl 2, 6-pyridinedicarboxylate, pyridine, or 2, 6-dithiomethylpyridine, respectively. A convenient procedure for halogen—halogen exchange is also described.
