Sojka, Stanley A.; Dinan, Frank J.; Kolarczyk, Robert published an article about the compound: 2-Chloropyridine 1-oxide( cas:2402-95-1,SMILESS:ClC1=CC=CC=[N+]1[O-] ).Category: isoxazole. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:2402-95-1) through the article.
13C NMR spectra of substituted pyridine N-oxides were examined and compared to the spectra of the corresponding free pyridine bases. The N-oxide functionality causes significant shielding at the C-2, C-4, and C-6 positions. This shielding was associated with electron d. donation by the N-oxide functionality to these positions. The N-oxide functionality also caused an enhancement of the substituent α-effect for -NMe2, -OMe, and -NO2 groups.
As far as I know, this compound(2402-95-1)Category: isoxazole can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
