Phosphorus Ligands from the Zhang Lab: Design, Asymmetric Hydrogenation, and Industrial Applications

Phosphorus Ligands from the Zhang Lab: Design, Asymmetric Hydrogenation, and Industrial Applications

Chiral phosphorus ligands have played a crucial role for the recent advances in asymmetric catalysis. This review summarizes chiral phosphorus ligands developed from the Laboratory of Professor Xumu Zhang in the latest 25 years. A number of iconic phosphorus ligands including bisphosphorus ligands with rigid chiral backbone such as BICP, PennPhos, TunePhos, and f-Binaphane, P-chiral bisphosphorus ligands TangPhos, Binapine, and DuanPhos, phosphine-phosphoramidte ligand YanPhos, noncovalent interaction-assisted ferrocenyl phosphorus ligand ZhaoPhos and WudaPhos, and tridentate ferrocenyl phosphorus ligands f-amphox are introduced, and their applications in asymmetric hydrogenation are emphasized.

Catellani Reaction: An Enabling Technology for Vicinal Functionalization of Aryl Halides by Palladium(0)/Norbornene Cooperative Catalysis

Catellani Reaction: An Enabling Technology for Vicinal Functionalization of Aryl Halides by Palladium(0)/Norbornene Cooperative Catalysis

The Catellani reaction, originally discovered by Catellani in 1997, and further developed by Catellani, Lautens and others, has emerged as a powerful strategy for the synthesis of polysubstituted arenes, which would be difficult to access via traditional methods. In this process, both ortho- and ipso-positions of aryl halides could be functionalized simultaneously with different electrophiles and terminating agents under the cooperative catalysis of palladium and norbornene (NBE). This review focuses on the significant progress of such transformations, and the section of typical Catellani reactions is divided into five parts according to the functionalization mode of ortho-C−H bond: alkylation, arylation, amination, acylation or thiolation.
