Tīmeklis2024. gada 15. aug. · 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 … Tīmeklisrac-BINAP-Pd-G3 is a third generation (G3) Buchwald precatalyst. t is air, moisture and thermally-stable and is highly soluble in a wide range of common organic solvents.
