Chalcogen-bonding interactions have recently gained considerable attention in the field of synthetic chemistry, structure, and bonding. Here, three organo-spiroselenuranes, having a Se(IV) center with strong intramolecular Se···N chalcogen-bonded interaction, been isolated by oxidation respective bis(2-benzamide) selenides derived from an 8-aminoquinoline ligand. Further, synthesized spiroselenuranes, when assayed for their antioxidant activity, show disproportionation hydrogen peroxide into...
Here, an α-selective Csp3-H bond functionalization of primary aliphatic alcohols with 1,4-naphthoquinones yielded Csp2-Csp2 coupled products driven by blue-LED light under catalyst, metal, base, and reagent-free conditions. In this transformation, cleavage three C-H bonds (two sp3-C-H, one sp2-C-H, O-H) four new formed, leading to fluorescent 2-acylated-1,4-naphthohydroquinones.
A novel organodiselenide, which mimics sulfhydryl oxidases and glutathione peroxidase (GPx) enzymes for oxidation of thiols by oxygen hydrogen peroxide, respectively, into disulfides has been presented. The developed catalyst oxidizes an array organothiols respective in practical yields using aerial O2 to avoid any reagents/additives, base, light source. synthesized diselenide also catalyzes the reduction peroxide water following GPx enzymatic catalytic cycle with a rate 49.65 ± 3.7 μM·min–1.
A one pot Cu(I)-assisted synthetic methodology has been developed for the preparation of biologically important C2-symmetric spirodiaza, benzyloxy and benzoxytelluranes from 2-bromo-N-aryl benzamides, benzyl alcohols, benzoic acids by using tellurium dianion (Te2-) under base-free conditions. Furthermore, C-C coupled biaryl 1,1'-diamides have prepared an excess Na2Te same reaction The synthesized spirodiazatelluranes served as a potent catalyst reduction H2O2 nitro-Michael reactions.
A series of trifunctional diselenides have been synthesized and exhibit Janus-faced antioxidant (hydrogen peroxide decomposer radical quencher antioxidant) oxidant (ROS generation) properties.
Abstract The presence of a chalcogen atom at the ortho ‐position phenols enhances their radical chain‐breaking activity. Here, copper(I)‐catalyzed reaction 2,6‐dibromo‐ and 2,6‐diiodophenols with diorganodiselenides has been studied for introduction two organoselenium substituents both ‐positions phenolic antioxidants, which afforded 2,6‐diorganoseleno‐substituted in 80–92% yields having electron‐donating CH 3 , electron‐withdrawing CN CHO functionalities. Additionally, groups also novel...
A series of novel copper(II) phenolate selenoether complexes have been synthesized and structurally characterized for the first time from copper(I) phenanthroline various substituted ortho-bisphenylselenide-phenol chelating ligands. The exhibit Jahn-Teller distortion in their geometry varied distorted square planar to octahedral by varying substituent bis-selenophenolate ligand. electrocatalyze hydrogen evolution reaction (HER) with a faradaic efficiency up 89%, it was observed that...
Organoselenium chemistry has gained much interest of researchers due to its applicability in synthetic and catalysis biology, particularly after the discovery selenocysteine ami...
The development of alternative energy sources is the utmost priority developing society. Unlike many prior homogeneous electrocatalysts that rely on a change in oxidation state metal center and/or electrochemically active ligand, here we report synthesis and structural characterization bimetallic zinc selenolate complex consisting redox silent ion tridentate ligand catalyzes reduction protons into hydrogen gas displays one highest reported TOF for TM-metal free centered HER catalyst, 509...
Selenium-derived electrocatalysts have been well explored for electrocatalytic hydrogen evolution reactions to mimic hydrogenase-like activity; however, the stability of these synthetic mimics is yet be enhanced.
Abstract The development of alternative energy sources is the utmost priority developing society. Unlike many prior homogenous electrocatalysts that rely on change in an oxidation state metal center and or electrochemically active ligand, synthesized novel bimetallic zinc selenolate complex consisting redox inactive ion catalytically ligand catalyzes electrochemical oxygen evolution from water with rate constant 7.28 s-1 at onset potential 1.028 V vs. NHE.

Here, first-ever an -selective Csp3‒H bond functionalization of primary aliphatic alcohols with 1,4-naphthoquinones yield-ed Csp2‒Csp2 coupled products is reported, driven by blue-LEDs light in photo-catalyst, metal, base, reagent free conditions. In this transformation, cleavage three C-H bonds (two sp3-C-H, one sp2-C-H, and O-H) four new formed, leading to fluorescent 2-acylated-1,4-naphthohydroquinones.
