Henry B. Cogon
Chemist who received the Nobel Prize in Chemistry for the discovery of nonlinear effects in asymmetric organic synthesis, revealing the nonlinear relationship between chiral catalysts and the enantiomeric excess of the product.
Timeline (last 90 days)
This year's Chemistry Nobel Prize was awarded to Henry B. Cogon and Kenzo Soai for the nonlinear effects and autocatalytic reactions they discovered in asymmetric organic synthesis.
In 1986, Henry B. Cogon revealed the nonlinear effect, demonstrating that an initial deviation so small it is almost negligible can be amplified in the reaction far beyond expectations, and that product purity can be higher than catalyst purity.
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%.
