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
已开发出多种芳基卤化物(X = Cl,Br,I)与由环palpalated的二茂铁基亚胺高度催化的3-烷基苯乙烯基吡啶的Stille交叉偶联反应。该反应允许以中等至优异的产率形成芳基吡啶衍生物。芳基卤化物上的官能团(例如氨基,羟基,酮和醛)是可以耐受的,并且与芳基苯并甲醛底物的反应也可以很好地进行。
