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
通过对映选择性的Pauson-Khand型反应催化剂成功完成了1-芳基烯丙基炔丙基醚的动力学拆分。具有慢速反应底物的选择是带有BINAP基配体且具有缺电子膦的阳离子铑(I),而带有BINAP基配体且具有富电子膦的中性铱(I)则提供了优异的结果。反应性底物。
