Buchwald-Hartwig Amination
ArBr + R2NH → ArNR2 + HBr
概述
The Buchwald-Hartwig reaction couples aryl halides with amines using a palladium catalyst to form aryl C-N bonds. This transformation, developed independently by Stephen Buchwald and John Hartwig in the 1990s, solved a long-standing challenge in organic chemistry. The reaction tolerates diverse functional groups.
日常示例
Many modern pharmaceuticals contain aryl amine bonds that were formed using this palladium-catalyzed coupling reaction.
