In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. 766-11-0, formula is C5H3BrFN, Name is 5-Bromo-2-fluoropyridine. For this reason, pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Computed Properties of 766-11-0.
Zhu, Qiming;Chen, Mingwei;Hu, Jinyu;Yang, Luyi research published 《 Facile N-Alkylation/N’-Arylation Process: A Direct Approach to Aromatic Aminoalkyl Amines》, the research content is summarized as follows. An intriguing C-N transformation involving a catalyst-free N-alkylation/N’-arylation process in a multicomponent reaction with secondary amines, cyclic tertiary amines and electron-deficient aryl halides has been described. In this case, the N-alkylation of secondary amines, utilizing cyclic tertiary amines as alkyl group sources, is enabled by a facile C-N cleavage. Such an operationally simple method could facilitate access to aromatic aminoalkyl amines, nitrogen-containing bioactive mols., in good to excellent yields.
Computed Properties of 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. , 766-11-0.
