Mild addition of nucleophiles to pyridine-N-oxides.

Allyn T Londregan et al.

Organic letters, 13(7), 1840-1843 (2011-03-08)

A general and facile one-pot procedure for the synthesis of 2-substituted pyridines from the corresponding pyridine-N-oxides and nucleophiles is presented as a mild alternative to S(N)Ar chemistry. A variety of nucleophiles and heterocyclic-N-oxides participate effectively in this transformation, which uses

Mechanistic studies on direct arylation of pyridine N-oxide: evidence for cooperative catalysis between two distinct palladium centers.

Yichen Tan et al.

Journal of the American Chemical Society, 134(8), 3683-3686 (2012-02-09)

Direct arylations of pyridine N-oxide (PyO), a convenient method to prepare 2-arylpyridines, catalyzed by Pd(OAc)(2) and PtBu(3) have been proposed to occur by the generation of a PtBu(3)-ligated arylpalladium acetate complex, (PtBu(3))Pd(Ar)(OAc) (1), and the reaction of this complex with

Pd-catalyzed oxidative CH/CH direct coupling of heterocyclic N-oxides.

Wei Liu et al.

Organic letters, 15(18), 4682-4685 (2013-09-12)

A highly efficient protocol for C-H/C-H cross-coupling has been found to occur between 2-aryl-1,2,3-triazole N-oxides and pyridine N-oxide derivatives. In addition, two homocoupling reactions of 2-substituted 1,2,3-triazole N-oxides and some pyridine N-oxide derivatives were developed. A possible pathway of C-H/C-H
