Buchwald-Hartwig Amination

ArBr + R₂NH → ArNR₂ + HBr

ภาพรวม

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.
