Integrating Enzymes with Photoredox Catalysis for Conversion of Nitriles into Fluorinated Products

open access: yesChemCatChem, EarlyView.
Herein, we describe a novel method for producing highly sought‐after fluorinated compounds through the integration of nitrilase enzymes and iridium photoredox catalysis in a convenient one‐pot reaction. Our chemo‐ biocatalytic methodology delivers a range of fluorinated and fluoroalkylated products from simple nitrile precursors, in good yields, at ...

Valorization of Glycerol Through 2,2,6,6‐Tetramethyl‐1‐Piperidine‐N‐Oxyl (TEMPO)‐Catalyzed Electrochemical Oxidation with High C3 Product Selectivity: Impact of Stirred Bulk Versus Flow Electrolysis

open access: yesChemElectroChem, EarlyView.
2,2,6,6‐tetramethyl‐1‐piperidine‐N‐oxyl‐catalyzed glycerol electrochemical oxidation proceeds with different selectivity when comparing bulk stirred and flow electrolysis. Conversion of glycerol to value‐added products is an attractive solution to the oversupply of this byproduct of biofuel production.

Sequential Carboborylation–Suzuki Coupling of α,β‐Unsaturated Tosylhydrazones: A Dual CC Bond‐Forming Strategy for Molecular Diversification

open access: yesChemistryEurope, EarlyView.
Structural diversity can be generated from α,β‐unsaturated carbonyls via N‐tosylhydrazones through a one‐pot‐three‐component photochemically promoted carboborylation/allylic Suzuki sequence. The wide availability and scope regarding each of three reaction partners: carbonyls, alkylboronic acids, and aryl halides, and the functionalities available in ...
