P. research published 《 Catalyst-free amination of 2-fluoropyridine and 2-fluoro-5-halopyridines with adamantane amines》, the research content is summarized as follows. Catalyst-free reactions of 2-fluoropyridine with amines and diamines bearing the adamantyl moiety at either the N atom or in the side chain were studied. Amines, which do not contain secondary alkyl substituents at the amino group, react with an excess of 2-fluoropyridine to give N-(pyridin-2-yl) derivatives in the yields from moderate to good. 2-Fluoro-5-halopyridines were found to be more reactive than 2-fluoropyridine.
COA of Formula: C5H3BrFN, 5-Bromo-2-fluoropyridine is a useful research compound. Its molecular formula is C5H3BrFN and its molecular weight is 175.99 g/mol. The purity is usually 95%.
5-Bromo-2-fluoropyridine is a boronic acid that has been shown to react with iodides and form 5-bromo-2-fluoroiodobenzene. The reaction of 5-bromo-2-fluoropyridine with benzene gives the same product as the reaction with 1,3,5-trioxane. The UV absorption of 5-bromo-2-fluoropyridine is found at 230 nm and 260 nm. It also has an absorption band in the infrared region at 1625 cm−1. Vibrational progressions have been observed for this molecule, which are due to dipole moments and electron density distributions in the molecule.
5-bromo-2-fluoropyridine is used in the synthesis of heteroaromatic and aniline derivatives of piperidines as potent ligands used for vesicular acetylcholine transport. , 766-11-0.
