Kinetic Resolutions by Enantioselective Pauson-Khand-Type Reaction

A kinetic resolution of 1‐arylallyl propargyl ethers by enantioselective Pauson–Khand‐type reaction catalysts was successfully carried out. While cationic rhodium(I) with a BINAP‐based ligand having an electron‐deficient phosphine is the choice for the slow reacting substrates, neutral iridium(I) wi...

Zusammenfassung:A kinetic resolution of 1‐arylallyl propargyl ethers by enantioselective Pauson–Khand‐type reaction catalysts was successfully carried out. While cationic rhodium(I) with a BINAP‐based ligand having an electron‐deficient phosphine is the choice for the slow reacting substrates, neutral iridium(I) with a BINAP‐based ligand possessing an electron‐rich phosphine provided excellent results for the more reactive substrates.
