Abstract

Based on the proposed mechanism, the electronic effects of various ligands on the stereoselectivity and reaction rate of the rhodium(I)-catalyzed asymmetric Pauson-Khand-type reaction were examined. We demonstrated that both the reaction rate and the enantioselectivity are significantly dependent on the electron density of the ligands; when ligands bearing deshielded phosphine were utilized, the reaction rate was slower, but the products were obtained with improved enantioselectivity.
