Technical Notes:

1.Chiral mixed secondary phosphine-oxide -phosphines: High-performing and easily accessible ligands for asymmetric hydrogenation.

2.Cobalt precursors for high-throughput discovery of base metal asymmetric alkene hydrogenation catalysts. 3.Regioconvergent and enantioselective rhodium-catalyzed hydroamination of internal and terminal alkynes: A highly flexible access to chiral pyrazoles.

4.Ligand for Ru-catalyzed Asymmetric Hydrogenation of Tetrasubstituted Acrylates .
