Regiospecific bromination of condensed tetralones via aryloxydifluoroboron chelates

, 1982
Bromination (Br2, CCl4) of the anthracenone derivative (1b) under thermal or photochemical conditions gives the expected bromo-compound (1d) whereas photochemical bromination of the aryloxydifluoroboron complexes (2a,b) gives products (2c,d) of benzylic ...

Impact of Organo‐Functionalization on the Light‐Driven Hydrogen Evolution Reactivity of Molecular Molybdenum Sulfides

Chemistry – A European Journal, EarlyView.
Organo‐functionalized molecular molybdenum sulfides were synthesized using bidentate N‐donor ligands and investigated as light‐driven homogeneous hydrogen evolution reaction (HER) catalysts. Trends observed in the HER activity of these catalysts were elucidated by combining photophysical, electrochemical and computational studies.

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

Chemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

Ratiometric pH‐Responsive and Biomimetic Microparticles for Quantitative Monitoring of Phagosomal Acidification

Chemistry – A European Journal, EarlyView.
A series of hydrosoluble BODIPY pH probes allows building biomimetic pH sensors based on micrometric oil‐in‐water droplets. The ratiometric fluorescence output offers quantitative information on the evolution of pH during phagosome maturation. ABSTRACT We present a modular biomimetic fluorescent sensing platform designed to precisely interrogate the ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.
