In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Carbon-13 nuclear magnetic resonance spectra of substituted pyridine N-oxides, published in 1979, which mentions a compound: 2402-95-1, Name is 2-Chloropyridine 1-oxide, Molecular C5H4ClNO, Reference of 2-Chloropyridine 1-oxide.

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.

We report herein a visible-light-mediated C-H alkylation of pyridine derivatives that proceeds by simple combination of a large variety of N-alkoxypyridinium ions with alkanes in the presence of 2 mol % of fac-Ir(ppy)3 under blue illumination. The mild reaction conditions together with the high group functional tolerance make of this process a useful synthetic platform for the construction of structurally strained heterocycles. Detailed mechanistic investigations, including d. functional theory calculations and quantum yield measurement, allowed us to understand factors controlling the reactivity and the selectivity of the reaction.
