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 ...

Effective reduction of N2O emission via combined plasma catalysis

open access: yesCatalysis Communications, 2023
N2O is a potent greenhouse gas that also causes devastating effects on the ozone layer. In this study, N2O decomposition is evaluated via thermal catalysis, plasma-alone and plasma catalysis, respectively. In thermal catalysis, N2O decomposition achieved
