Electrochemical Regioselective Chalcogenocyclizations of 2‐Alkynylbenzamides in Flow

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
A sustainable electrochemical method enables regioselective 6‐endo‐dig chalcogeno‐cyclizations of ortho‐alkynylbenzamides in continuous flow. Using diphenyl diselenide as an electroactive coupling partner, the process avoids metals and stoichiometric oxidants, offering scalable access to selenium‐containing heterocycles.

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles

Endogenous Labelling of Extracellular Vesicles and Image Capture of Their Interactions With Acceptor Cells

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Isolation and characterisation of endogenously labelled extracellular vesicles (EVs) from donor cells are timelapse imaged using intensity and lifetime microscopies to capture EV contact with filopodia and the plasma membrane (PM) of acceptor cells. Accumulation of EVs within and around filipodia could be observed and following passage through the PM ...
