The … In organic chemistry, the Buchwald–Hartwig amination is a chemical reaction for the synthesis of carbon–nitrogen bonds via the palladium-catalyzed coupling reactions of amines with aryl halides. Although Pd-catalyzed C-N couplings were reported as early as 1983, Stephen L. Buchwald and John F. … See more The first example of a palladium catalyzed C–N cross-coupling reaction was published in 1983 by Migita and coworkers and described a reaction between several aryl bromides and N,N-diethylamino-tributyl See more Because of the ubiquity of aryl C-N bonds in pharmaceuticals and natural products, the reaction has gained wide use in synthetic organic chemistry, with application in many See more Under conditions similar to those employed for amination, alcohols can be coupled with aryl halides to produce the corresponding aryl ethers. This serves as a convenient … See more The reaction mechanism for this reaction has been demonstrated to proceed through steps similar to those known for palladium catalyzed C-C coupling reactions. Steps … See more Although the scope of the Buchwald–Hartwig amination has been expanded to include a wide variety of aryl and amine coupling partners, the conditions required … See more • Buchwald–Hartwig Coupling – Recent Literature • Buchwald–Hartwig Chemistry Ian Mangion MacMillan Group Meeting July 30, 2002 Link • Buchwald–Hartwig reaction Precious-Metal catalysts from Acros Organics for coupling reactions in organic synthesis See more
