General description
4-Methoxypyridine N-oxide hydrate is a substituted pyridine N-oxide. It forms 1:1 complexes with MnCl2 and NiCl2 salts. Mechanism of reaction between 4-methoxypyridine N-oxide hydrate and bis(pinacolato) (diboron reagent) in CD3CN has been studied by NMR. It forms 1:1 complex with 2,4-dinitrophenol due to the formation of intermolecular hydrogen bond between the O-H and N-O groups.
Application
4-Methoxypyridine N-oxide hydrate may be used in chemical synthesis.

Facile reduction of alkylamino-, anilino-, and pyridyl-N-oxides can be achieved via the use of diboron reagents, predominantly bis(pinacolato)- and in some cases bis(catecholato)diboron [(pinB)(2) and (catB)(2), respectively]. Reductions occur upon simply mixing the amine N-oxide and the diboron reagent in
