Merging Biocatalysis and Chemocatalysis in Flow: State‐of‐the‐Art and Future Directions for Sustainable Synthesis

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...

An Intramolecular Frustrated Lewis‐Pair Based on a Bismuth(III) Acid Site

ChemistryEurope, Volume 4, Issue 9, September 2026.
Triflate ligands were the key for the design of a frustrated Lewis pair (FLP) that utilizes a soft bismuth(III) center as the Lewis acidic site. The acceptor properties are based on empty p orbitals generated through the ionic binding of the triflate anions to the Bi center.

Oxidative 3,3,3-trifluoropropylation of arylaldehydes

Beilstein Journal of Organic Chemistry, 2013
A reaction between (E)-trimethyl(3,3,3-trifluoroprop-1-en-1-yl)silane (1) and arylaldehydes 2 was triggered by fluoride anions to afford aryl 3,3,3-trifluoropropyl ketones 3 in moderate to good yield.

Organo-Fluorine Compounds as Artificial Blood Substitute

Defence Science Journal, 1980
The rate of fluoro-carbon compounds as artificial substitute for blood has been discussed. Blood is a complicated body fluid. At first glance it seems impossible that such a complicated body fluid can be replaced by artificial synthesized fluids or any substitute for this can be synthesized.

Investigation of Electro‐Oxidation and Ozonation for Removal of Organics in Wastewater Derived From Recycling Process for Lithium‐Ion Batteries

CleanMat, Volume 3, Issue 3, Page 170-183, September 2026.
To develop recycling processes for lithium‐ion batteries, wastewater treatment for the removal of organic compounds originating from the electrolyte was investigated using electro‐oxidation and ozonation. Based on the results, this paper proposes a process which combines these two methods to remove alcohols derived from the solvent and additives ...
