It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. 766-11-0, formula is C5H3BrFN, Name is 5-Bromo-2-fluoropyridine. It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell. Product Details of C5H3BrFN.
Wang, Xie;Davies, Geraint H. M.;Koschitzky, Adriel;Wisniewski, Steven R.;Kelly, Christopher B.;Molander, Gary A. research published 《 Photoredox Catalysis Enables Access to N-Functionalized 2,1-Borazaronaphthalenes》, the research content is summarized as follows. The synthesis and use of a class of 2,1-borazaronaphthyltrifluoroborate reagents that provide a general solution to the challenge of N-functionalization of the 2,1-borazaronaphthalene core is described. By adorning the N of this core with a trifluoroboratomethyl unit, a suite of odd-electron processes can be executed, installing motifs that would otherwise be inaccessible using a two-electron approach. This process enables rapid annulation, furnishing a heretofore unknown polycyclic B-N species.
766-11-0, 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. , Product Details of C5H3BrFN
