Organocatalytic asymmetric fluorination of α-chloroaldehydes involving kinetic resolution

Beilstein Journal of Organic Chemistry, 2014
In a previous study it was shown that the enantioselective α-fluorination of racemic α-chloroaldehydes with a chiral organocatalyst yielded the corresponding α-chloro-α-fluoroaldehydes with high enantioselectivity.

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

CleanMat, EarlyView.
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 ...

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Deoxygenative gem-difluoroolefination of carbonyl compounds with (chlorodifluoromethyl)trimethylsilane and triphenylphosphine

Beilstein Journal of Organic Chemistry, 2014
Background: 1,1-Difluoroalkenes cannot only be used as valuable precursors for organic synthesis, but also act as bioisosteres for enzyme inhibitors. Among various methods for their preparation, the carbonyl olefination with difluoromethylene phosphonium

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Hot-Carrier Stressing of NPN Polysilicon Emitter Bipolar Transistors Incorporating Fluorine

, 2003
The effects of fluorine on the hot-carrier induced degradation in low-thermal-budget polysilicon emitter NPN bipolar transistors have been examined. Forward Gummel plots, base emitter (BE) diode characteristics, and stress currents were measured during ...
