Chiral imidate–ferrocenylphosphanes: synthesis and application as P,N-ligands in iridium(i)-catalyzed hydrogenation of unfunctionalized and poorly functionalized olefins
Chiral imidate–ferrocenylphosphanes: synthesis and application as P,N-ligands in iridium(i)-catalyzed hydrogenation of unfunctionalized and poorly functionalized olefins
The present invention relates to a use of a cyclic imidate as a ligand for catalysis in which the ligand contains sub-structure (Y) as a minimal structural motive, wherein the carbon atoms and the nitrogen atom can be optionally substituted by a chemical substituent.

A small library of chiral imidateâferrocenylphosphane ligands was efficiently synthesized (8 examples) and evaluated in the iridium(I)-catalyzed hydrogenation of unfunctionalized and poorly functionalized olefins. These catalysts perform very well in a range of examples (yields and ee's up to 100%).
