2-Bromopyridine, 99%

2. Reaction with n-BuLi gives 2-lithio-pyridine. Subsequent reaction at low temperatures with PCl₃ gives, as the major product, 2,2'-bipyridine, along with a low yield of the expected tris(2-pyridyl)phosphine. POCl₃ or SOCl₂ also promote the symmetrical coupling reaction: Heteroatom. Chem., 5, 409 (1994). In contrast, reaction with LDA in THF at -78° results in lithiation at the 3-position, giving access to 3-substituted 2-bromopyridines: Synthesis, 235, 237 (1982). See also: Org.
