Effect of Steric and Electronic Properties of Palladium Complexes with Bidentate Diphosphine Ligands on the Basis of Diphenyl Oxide on Arylation of Amines
A new procedure has been developed for the preparation of new bidentane diphosphine ligands, 2,2'-diphosphinodiphenyl ethers containing various substituents on the phosphorus, which differ in both electron-donor and steric parameters.
