Computed Properties of C5H4ClNO. 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 Periselectivity between the [1,4] and [3,3] thermal sigmatropic rearrangements of 2-allyloxypyridine N-oxides. Author is Alker, David; Ollis, W. David; Shahriari-Zavareh, Hooshang.
Thermal rearrangement of 2-allyloxpyridine N-oxides I (R = H, OMe, NO2) yields N-allyloxy-2-pyridones II and 3-allyl-N-hydroxy-2-pyridones III. These transformations are regiospecific and on this basis it is proposed that the reactions involve concerted [1,4] and [3,3] sigmatropic rearrangements. Supporting evidence based on solvent effects, temperature effects, and substituent effects is given.
