The chemical essence of the nonlinear effect lies in the fact that chiral catalyst molecules can form dimers or multimers, and different aggregation states have completely different catalytic activity and chiral selectivity.

UnverifiedKagan proposed that two or more chiral ligands can simultaneously bind to a metal to form a catalyst, and when the activity of the heterochiral complex is far lower than that of other types, the ratio of product enantiomers will exceed the ratio of the catalyst itself—a phenomenon known as the positive nonlinear effect.78% similarVerifiedSoai developed asymmetric autocatalytic reactions, in which the reaction product itself acts as its own catalyst, capable of amplifying a tiny chiral bias starting from achiral raw materials.70% similarUnverifiedIf the product is also chiral and preferentially catalyzes the formation of molecules with the same chirality as itself, this constitutes chiral autocatalysis.68% similarUnverifiedAsymmetric catalysis is one of the most effective strategies for obtaining single enantiomers in modern organic synthesis, and can be divided into three major categories: enzymatic catalysis, metal catalysis and organocatalysis by small organic molecules, with advantages such as high atom economy, few steps and little waste.66% similarUnverifiedIn the positive nonlinear effect mechanism, homochiral combinations (R-R or S-S) have higher asymmetric induction ability, while heterochiral combinations (R-S) have lower activity, enabling catalysts of modest chiral purity to still yield high-purity products.65% similar
