title: Palladium-catalyzed rearrangement/arylation of 2-allyloxypyridine leading to the synthesis of N-substituted 2-pyridones.
abstract: [reaction: see text] The Pd-catalyzed one-pot rearrangement/arylation of 2-allyloxypyridine is described. The catalyst/base combination of Pd[P(t-Bu)(3)](2)/Ag(2)CO(3) was found to be optimal for this one-pot rearrangement/arylation. The initial rearrangement of 2-allyloxypyridine was found to be catalyzed by both Pd(0) and Pd(II) complexes with different mechanisms.
