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.
