Autocatalysis in Chemical Networks: Unifications and Extensions [PDF]
, 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.

Autocatalysis in Eschenmoser Coupling Reactions [PDF]
Chemistry – 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.

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

Ecological autocatalysis [PDF]
Ecological monographs, 2018 Ecosystems comprise flows of energy and materials, structured by organisms and their interactions. Important generalizations have emerged in recent decades about conversions by organisms of energy (metabolic theory of ecology) and materials (ecological stoichiometry).

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

Mathematical Analysis of a Prototypical Autocatalytic Reaction Network
Life, 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.
