Name: 4-Chloro-2-fluoropyridine. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 4-Chloro-2-fluoropyridine, is researched, Molecular C5H3ClFN, CAS is 34941-92-9, about One-Pot Approach for SNAr Reaction of Fluoroaromatic Compounds with Cyclopropanol. Author is Jin, Hao; Gao, Zhuo; Zhou, Shaodong; Qian, Chao.
A novel method for preparation of aryl cyclopropyl ethers I [Ar = 1-ClC6H4, 2-O2NC6H4, 4-chloro-2-pyridyl, etc.] via nucleophilic aromatic substitution reaction (SNAr) of fluoroarom. compounds with cyclopropanol under relatively mild conditions was developed. The reaction was performed at 75 °C with Cs2CO3 as the base and DMF as solvent, after 6 h the yield was up to 90%. Finally, various fluoroarom. compounds were employed as substrates for a test that proved a wide application scope of the method.
