Mo-Phos: A New, Tri(tert-alkyl)phosphine Ligand for the Palladium-Catalyzed Amination of Haloarenes
An efficient and straightforward method for the direct amination of aryl halides has been developed by a team of researchers at Takasago International Corp. The method relies on the use of Mo-Phos, di-tert-butyl(2,2-diphenyl-1-methyl-1-cyclopropyl)phosphine, as a new, hybrid phosphine ligand for the palladium catalyst. Read More
