Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-Chloropyridine 1-oxide, is researched, Molecular C5H4ClNO, CAS is 2402-95-1, about Research on synthesis of 2-chloro-4-nitropyridine-N-oxide. Author is Li, Quanliang; Wang, Jun; Li, Shujing.
2-Chloro-4-nitropyridine-N-oxide was synthesized from 2-chloropyridine by N-oxidation and mixed acid nitrifying with one pot reaction. The intermediate yield of 2-chloropyridine-N-oxide was 96.5% when n(2-chloropyridine):n(H2O2):n(CH3COOH) = 1:3.5:1.5, the reaction temperature was 80°C and the reaction time was 3 h. Synthetic liquid proceeded nitration reaction directly after enrichment. The production yield of 2-chloro-4-nitropyridine-N-oxide was 85.8% when n(2-chloropyridine-N-oxide):n(HNO3) = 1:3.5, V(H2SO4)/V(HNO3) = 1:1, the reaction temperature was 80°C and the reaction time was 6 h. The structures of intermediate and target product were confirmed by M.p., IR, MS and elemental anal. The final product was gained.
There is still a lot of research devoted to this compound(SMILES：ClC1=CC=CC=[N+]1[O-])Product Details of 2402-95-1, and with the development of science, more effects of this compound(2402-95-1) can be discovered.
