A Self‐Enhanced Tandem Catalytic System for Olefin‐to‐Diol Conversion Powered by Single‐Atom Fe Catalysts With In Situ Generated Acid

EcoEnergy, EarlyView.
A single‐atom iron catalyst with well‐defined Fe–N4 sites enables a tandem epoxidation‐hydrolysis process for converting terminal olefins to 1,2‐diols. The in situ‐generated isobutyric acid drives the hydrolysis step, affording broad substrate scope and excellent recyclability.

Glutaraldehyde-crosslinked Rhizopus oryzae whole cells show improved catalytic performance in alkene epoxidation

Microbial Cell Factories, 2023
Background Existing methods for alkene epoxidation are based on lipase-catalysed perhydrolysis. However, the inactivation of the expensive lipase enzyme is problematic for enzymatic epoxidation at large scales due to the use of hydrogen peroxide and ...

Stereochemistry of Epoxidation of Some Caryophyllenols

, 2016
Epoxidation of the caryophyllene allylic alcohols 3−5 by tert-butyl hydroperoxide/vanadyl acetylacetonate afforded the epoxides 6a, 7, and 8, respectively. The tetracyanoethylene-catalyzed solvolysis shed some light on the stereochemistry of epoxidation.

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

Food Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic
