Stereodivergent Catalysis [PDF]

open access: yesChemical Reviews, 2018
This review covers diastereo- and enantiodivergent catalyzed reactions in acyclic and cyclic systems using metal complexes or organocatalysts. Among them, nucleophilic addition to carbon-carbon and carbon-nitrogen double bonds, α-functionalization of carbonyl compounds, allylic substitutions, and ring opening of oxiranes and aziridines are considered ...

Reversible catalysis [PDF]

open access: yesNature Reviews Chemistry, 2021
We describe as 'reversible' a bidirectional catalyst that allows a reaction to proceed at a significant rate in response to even a small departure from equilibrium, resulting in fast and energy-efficient chemical transformation. Examining the relation between reaction rate and thermodynamic driving force is the basis of electrochemical investigations ...

Ferrocene-derived P,N ligands : synthesis and application in enantioselective catalysis [PDF]

open access: yes, 2013
Due to their unique steric and electronic properties, air-stability and modular structure, chiral hybrid P,N-ferrocenyl ligands play a prominent role in the field of asymmetric catalysis.

Accelerated discovery of multi-elemental reverse water-gas shift catalysts using extrapolative machine learning approach

open access: yesNature Communications, 2023
Designing novel catalysts is key to solving many energy and environmental challenges. Despite the promise that data science approaches, including machine learning (ML), can accelerate the development of catalysts, truly novel catalysts have rarely been ...

Search for Nucleon Decays induced by GUT Magnetic Monopoles with the MACRO Experiment [PDF]

open access: yes, 2002
The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion-number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon decay).

Magnetic catalysis in flavored ABJM [PDF]

open access: yes, 2014
We study the magnetic catalysis of chiral symmetry breaking in the ABJM Chern-Simons matter theory with unquenched flavors in the Veneziano limit. We consider a magnetized D6-brane probe in the background of a flavored black hole which includes the ...

Diastereodivergent Catalysis

open access: yesJACS Au, 2023
Alongside enantioselective catalysis, synthetic chemists are often confronted by the challenge of achieving catalyst control over the relative configuration to stereodivergently access desired diastereomers. Typically, these approaches iteratively or simultaneously control multiple stereogenic units for which dual catalytic methods comprising ...
