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. , Category: pyridine-derivatives
