Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences [PDF]

open access: yesChemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Autocatalysis in Chemical Networks: Unifications and Extensions [PDF]

open access: yes, 2020
Autocatalysis is an essential property for theories of abiogenesis and chemical evolution. However, the different formalisms proposed so far seemingly address different forms of autocatalysis and it remains unclear whether all of them have been captured.

Ni-Catalyzed Arylbenzylation of Alkenylarenes. Kinetic Studies Reveal Autocatalysis by ZnX2 and 3-Fold Catalytic Rate Increase [PDF]

open access: yes, 2021
We report a Ni-catalyzed regioselective arylbenzylation of alkenylarenes with benzyl halides and arylzinc reagents. The reaction furnishes differently substituted 1,1,3-triarylpropyl structures that are reminiscent of the cores of oligoresveratrol ...

The problem of the autocatalytic origin of culture in Juri Lotman’s cultural philosophy

open access: yesSign Systems Studies, 2005
The origin of culture remains in the sphere of hypotheses. Although the hypotheses derive from two presumptions: first, how the structure of culture is envisaged, and secondly, how culture is thought to function.

Bandgap‐Coupled Template Autocatalysis toward the Growth of High‐Purity sp2 Nanocarbons

open access: yesAdvanced Science, 2021
Extraordinary properties and great application potentials of carbon nanotubes (CNT) and graphene fundamentally rely on their large‐scale perfect sp2 structure.

Autocatalysis in Eschenmoser Coupling Reactions [PDF]

open access: yesChemistry – A European Journal, 2023
AbstractThe Eschenmoser coupling reaction (ECR) of thioamides with electrophiles is believed to proceed via thiirane intermediates. However, little is known about converting the intermediates into ECR products. Previous mechanistic studies involved external thiophiles to remove the sulfur atom from the intermediates.

Model of the nonlinear reaction system with autocatalysis and autoinhibition: Stability of dynamic states [PDF]

open access: yesHemijska Industrija, 2012
Self-regulation, achieved through positive (autocatalytic) or negative (autoinhibitory) feedback is commonly encountered in natural, technological and economic systems.

Autocatalysis-Driven Clock Reaction III: Clarifying the Kinetics and Mechanism of the Thiourea Dioxide–Iodate Reaction in an Acidic Medium [PDF]

open access: yes, 2019
The thiourea dioxide–iodate reaction has been reinvestigated spectrophotometrically under acidic conditions using phosphoric acid–dihydrogen phosphate buffer within the pH range of 1.1–1.8 at 1.0 M ionic strength adjusted by sodium perchlorate and at 25 °

Mathematical Analysis of a Prototypical Autocatalytic Reaction Network

open access: yesLife, 2019
Network autocatalysis, which is autocatalysis whereby a catalyst is not directly produced in a catalytic cycle, is likely to be more common in chemistry than direct autocatalysis is.
