Palladium‐Catalyzed (<i>N</i>‐Oxido‐2‐pyridinyl)methyl Transfer from 2‐(2‐Hydroxyalkyl)pyridine <i>N</i>‐Oxide to Aryl Halides by β‐Carbon Elimination

Abstract

Successful transfer application: (N-Oxido-2-pyridinyl)methyl transfer from (2-hydroxyalkyl)pyridine N-oxide derivatives to aryl bromides proceeds under palladium catalysis through β-carbon elimination involving cleavage of an unstrained C(sp3)C(sp3) bond, yielding 2-benzylpyridine N-oxide derivatives.
