The classic and commercially available bidentate phosphine ligand 1,3-bis(diphenylphosphino)propane (dppp) was synthesized using nearly all benchtop techniques (Scheme 3a). A ligand could be monodentate, meaning it binds through a lone pair on a single atom.It could be bidentate, meaning it binds through lone pairs on two different atoms.It could even be tridentate, with three atoms bearing their own lone pairs, tetradentate, and so on. Based on a phosphine-phosphoramidite lead structure, a modular synthetic pathway was used to synthesise different types of mixed bidentate phosphine ligands.
