Application of 2402-95-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Chloropyridine 1-oxide, is researched, Molecular C5H4ClNO, CAS is 2402-95-1, about Study in synthesis of N-oxide-2-pyridine phenyl sulfide derivative. Author is Li, Shuyan.
N-oxide-2-pyridine Ph sulfide derivatives were prepared by mercapto-reaction of 4-methylthiophenol or 4-chlorothiophenol with N-oxide-2-chloropyridine prepared by oxygenation of 2-chloropyridine with 30% H2O2 in acetic acid. The reaction of nucleophilic displacement on the ring of 2-chloropyridine was discussed. The structures of the synthesized compounds were characterized by IR, 1H NMR, and 13C NMR.
