Facile synthesis of 3-arylpyridine derivatives by palladacycle-catalyzed Stille cross-coupling reaction

Abstract

The Stille cross-coupling reaction of a variety of aryl halides (X=Cl, Br, I) with 3-alkylstannylpyridines highly catalyzed by cyclopalladated ferrocenylimine has been developed. This reaction allows formation of arylpyridine derivatives in moderate to excellent yields. Functional groups on aryl halides, such as amino, hydroxyl, keto, and aldehyde are tolerated and the reactions with arylbenzoxale substrates also proceed well. © 2012 Elsevier Ltd.
