Henry B. Kagan
A French chemist and pioneer in the field of asymmetric catalysis, known for discovering nonlinear effects in asymmetric reactions (the Kagan nonlinear effect). He is one of the recipients of the 2026 Nobel Prize in Chemistry.
Core Facts
The 2026 Nobel Prize in Chemistry was awarded to French chemist Henri Kagan and Japanese chemist Kenso Soai in recognition of their discovery of nonlinear effects and autocatalytic reactions in asymmetric organic synthesis.
In 1986, Kagan reported that in certain catalytic systems, the relationship between catalyst ee and product ee is nonlinear, that is, a positive nonlinear effect or a negative nonlinear effect.
Chemists Henri Kagan and Kensō Soai won the 2026 Nobel Prize in Chemistry for revealing the selection mechanism of molecular chirality (according to a YouTube science current-affairs channel).

The research of Kagan and Soai revealed that under certain conditions, a small excess of one chiral molecule can trigger a chain reaction, greatly amplifying the proportion of that chirality in the product, far beyond the proportion initially input.
Kagan found that in certain asymmetric catalytic systems, using a catalyst with a low ee value can nonetheless yield a product with a high ee value, and even a positive nonlinear effect occurs, in which a small amount of chiral catalyst can induce a large amount of chiral product.
