Accumulation of organophosphorus pollutants in adipose tissue of obese women - metabolic alterations.

Environmental Research, 2023
Organophosphorus pesticides (OPPs) and organophosphate esters (OPEs) are organophosphorus compounds created as substitutes for persistent environmental pollutants, namely organochlorines pesticides and brominated flame retardants, respectively.

Organophosphorus-Catalyzed “Dual-Substrate Deoxygenation” Strategy for C–S Bond Formation from Sulfonyl Chlorides and Alcohols/Acids

, 2023
A green method to construct C–S bonds using sulfonyl chlorides and alcohols/acids via a PIII/PVO catalytic system is reported. The organophosphorus-catalyzed umpolung reaction promotes us to propose the “dual-substrate deoxygenation” strategy. Herein, we
