The application of this and other related P-N ligands to the copper catalyzed beta-borylation of alpha,beta-unsaturated esters resulted in conversions of up to 100% and ee values of up to 79%. A diastereomerically pure palladacycle of the new ligand was characterised by X-ray crystallography....
CatalysisAlkenesTwo new classes of proline-based P,O and P,N ligands were prepared and applied in the iridium-catalyzed asymmetric hydrogenation of alkenes. Both types of ligands induced high enantioselectivities in the hydrogenation of trisubstituted CC bonds. Iridium complexes derived from P,O ...
Phosphorus- and nitrogen-containing ligands are among the most important and widely used ligands for transition-metal homogeneous catalysis (asymmetric or not). The present review combines information on the recent advances for the syntheses of these heterodentate ligands, their coordination chemistry with...

[reaction: see text] A new class of cyclohexane-based P,N-ligands is readily obtained through aziridine ring opening with suitable phosphorus nucleophiles under acidic conditions. trans-1-Amino-2-diphenylphosphinocyclohexane is resolved with tartaric acid to give the final product in >99% ee. The...
