Abstract
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.
