[摘要]：Gas-phase equil. measurements were used to det. the stereoselectivity of binding the enantiomers of 1-phenylethanol to Mn/salen asym. epoxidn. catalysts. There is significant selectivity in the gas-phase binding, and the results are compared to data from condensed-phase epoxidns. The study demonstrates the utility of a novel internal std. approach that allows for rapid, accurate measures of the stereoselectivity of gas-phase ligand binding. Also, the data suggest that gas-phase binding stereoselectivity could be a potential predictor of condensed-phase enantioselectivity. |
