Unverified50% confidenceFactExact time
Cogon discovered that the ee value of the product and the ee value of the catalyst can exhibit a nonlinear relationship; for example, using a chiral catalyst with an ee value of only 10% may still yield a product with an ee value as high as above 90%.

UnverifiedEnantiomeric excess (ee value) is the core metric for measuring the efficiency of chiral synthesis; if the R-form accounts for 99.5% and the S-form accounts for 0.5%, the ee value is 99%.62% similarUnverifiedEnantiomeric excess (ee value): ee = 100% means the reaction produces only one enantiomer, while ee = 0% means the two enantiomers are present in equal amounts (a racemic mixture).61% similarUnverifiedEnantiomeric excess (ee) is the standard measure of chiral purity; if a product contains 90% right-handed and 10% left-handed forms, then ee = 80%.60% similarUnverifiedStarting from a catalyst with an enantiomeric excess of only 0.00005%, Soai demonstrated that after repeating the reaction three times, the enantiomeric excess of the product can be raised to above 99.5%.58% similarUnverifiedIn the Soai reaction, even if the initial chiral imbalance is less than 0.00005%, the enantiomeric excess (ee value) of the product can exceed 99.5% after multiple cycles.57% similar
