WebAug 15, 2024 · Buchwald-Hartwig amination is a palladium-catalyzed cross-coupling reaction of amines and aryl halides that results in formation of C-N bonds. It was first introduced by Kosugi, Kameyama and Migita in 1983[1]. It was a reaction using 1 mol% PdCl2(P (o-Tolyl3)2 with the addition of aryl bromides and N,N-diethylamino-tributyltin in … WebJohn F.

WebMetal-catalyzed C–H borylation reactions Aliphatic C–H borylation. As first described by Hartwig, alkanes can be selectively borylated with high selectivity for the primary C–H bond using Cp*Rh(η 4-C 6 Me 6) as the catalyst. Notably, selectivity for the primary C–H bond is exclusive even in the presence of heteroatoms in the carbon-hydrogen chain. WebThe Hartwig group found that "reductive elimination can occur from either a four-coordinate bisphosphine or three-coordinate monophosphine arylpalladium amido complex. Eliminations from the three-coordinate compounds are faster. Second, β-hydrogen elimination occurs from a three-coordinate intermediate.
WebRegioselectivity of the borylation of alkanes and arenes † John F.
