Electron Paramagnetic Resonance Detection of Singlet Oxygen: Opportunities and Pitfalls of Sterically Hindered Amine Trapping Agents

ChemPlusChem, EarlyView.
This study reveals systematic errors in singlet oxygen (1O2) quantification using electron paramagnetic resonance (EPR) with 4‐substituted 2,2,6,6‐tetramethylpiperidine (TEMP) derivatives. N‐oxyl radical impurities can artificially elevate the characteristic 1O2 EPR signal, while aqueous‐phase side reactions convert TEMP and N‐oxyl TEMP derivatives ...

Rational Modulation of Excited‐State Intramolecular Proton Transfer, Aggregation‐Induced Emission, and Intramolecular Motion on Polysubstituted Imidazoles

ChemPhotoChem, EarlyView.
Precise modulation of the excited‐state intramolecular proton transfer (ESIPT) process was achieved using a newly synthesized family of N‐substituted imidazoles. Combined experimental and theoretical approaches reveal how N‐alkyl and 2‐(methoxy)phenyl modulate enol‐keto equilibrium, molecular conformation, and emission behavior.

Electrochemical Three‐Component Synthesis of Vinyl Sulfonamides via Decarboxylative Sulfonylation of Cinnamic Acids

ChemSusChem, EarlyView.
An efficient, metal‐free electrochemical three‐component reaction of cinnamic acids, SO2, and amines to access (E)‐β‐styryl sulfonamides is reported. Utilizing graphite electrodes and SO2 stock solutions, this decarboxylative protocol proceeds under mild conditions with high regio‐ and stereoselectivity.
