WebAug 15, 2024 · 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 toluene solvent heated at 100°C for three hours. The resulting data showed that only nonsubstitued bromobenzene would give the product with a high yield. WebUnlike organic molecules that are chiral because of a carbon with four different substituents, BINAP looks symmetrical, but it’s the restricted rotation around a single bond, an axis that connects ...
