WebMar 13, 2024 · We therefore checked further salts, first with the tetrabutylammonium cation, and then with Na + as the counterion. Successful exchange reactions could be performed using Pd 2 (dba) 3 as the Pd source and Davephos as the ligand in DMSO, as previously found for Buchwald–Hartwig type cross-couplings (Ref. [ 16 ]). 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 …
