P-Phos: a family of versatile and effective atropisomeric dipyridylphosphine ligands in asymmetric catalysis.

Jing Wu et al.

Accounts of chemical research, 39(10), 711-720 (2006-10-18)

This Account outlines our efforts in the design and synthesis of a family of highly effective atropisomeric dipyridylphosphine ligands (P-Phos and its variants) and in the development of their widespread applications in transition-metal-catalyzed asymmetric reactions including hydrogenation, hydrosilylation, and C-C

Articles

P-Phos, PhanePhos and BoPhoz™ Ligands

The P-Phos ligand family was developed by Professor Chan of Hong Kong Polytechnic University and licensed to JM CCT in 2002. P-Phos is an atropisomeric biaryl bisphosphine with the unique feature of incorporating two methoxy-substituted pyridine rings in the backbone.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
