Henry Kogan's contribution is asymmetric synthesis: in a chemical reaction, the left-handed and right-handed versions each account for 50% in the initial state, and by artificially increasing the proportion of one version (for example, from 50:50 to 51:49, i.e., an excess of 2%), he was able to observe significant changes in the product.

UnverifiedThe 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.62% similarUnverifiedIn 1986, Kagan published findings on nonlinear effects, discovering that product ratios do not change linearly with the catalyst but follow a curve, which can significantly increase the proportion of the target mirror-image molecule.61% similarUnverifiedHenri B. Kagan revealed a nonlinear effect: under certain conditions, a tiny difference in catalyst chirality can have a huge impact on the proportion of enantiomers in the product.59% similarUnverifiedKagan challenged the dogma that the ratio of product enantiomers is linearly related to the ratio of the catalyst, proposing that two or more chiral ligands can simultaneously bind to the metal center of a catalyst.58% similarUnverifiedKagan has done pioneering work in the field of chiral phosphine ligands, which can selectively generate products of a specific chiral configuration in metal-catalyzed reactions.57% similar
