The solubilization of diphenyl diselenide in surfactant solutions

Journal of Dispersion Science and Technology, 2021
Solubilization of diphenyl diselenide (DPDS) was studied in CTAB, OPE-10 and SDS surfactant solutions at 298 K. Solubility of DPDS increases with increase in the surfactant concentration due to its solubilization in micelles. UV-Vis, H1 NMR and FT-IR spectroscopy was used to study the interaction, location of diphenyl diselenide in the micelle.

Electrochemically Driven Regioselective Radical Functionalization of Allenes: Scope and Mechanistic Insights [PDF]

Advanced Science, EarlyView.
Allenes emerge as powerful platforms for electrochemical functionalization through radical pathways. Selective radical addition at the central carbon triggers anodic oxidation and intramolecular cyclization, enabling efficient synthesis of oxazolines and oxazolidine‐2‐imines without external oxidants.

Chemical modifications of diphenyl diselenide enhance its anti-Sporothrix spp. activity and exhibit synergism with itraconazole. [PDF]

Braz J Microbiol
Sporotrichosis is a globally distributed subcutaneous mycosis caused by fungi belonging to the Sporothrix genus. The limitations of current treatment options for sporotrichosis have driven an urgent search for new antifungal drugs.

NiH‐Catalyzed Enantio‐ and Regioselective Hydroselenylation of Unactivated Alkenes [PDF]

Advanced Science, EarlyView.
Nickel‐hydride‐catalyzed enantio‐ and regioselective hydroselenylation of unactivated alkenes provides access to chiral organoselenium compounds. Enantiodetermining Ni–H insertion followed by single‐electron diselenide activation generates selenyl radical.

Upper Rim-Bridged Calix[4]arenes via Cyclization of meta Alkynyl Intermediates with Diphenyl Diselenide [PDF]

Molecules
A Sonogashira coupling of meta-iodocalix[4]arene with various terminal acetylenes confirmed that the meta position of calixarene is well addressable, and that both thermal and microwave protocols led to good yields of alkynylcalixarenes.
