Frontiers in Chemistry, 2019 One of the limiting factors in the development of magnesium batteries is the reversibility of magnesium electrodeposition and dissolution at the anode. Often irreversibility is related to impurities and decomposition.

Angewandte Chemie, EarlyView.A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

Enantioselective Synthesis of cis-Decalins Using Organocatalysis and Sulfonyl Nazarov Reagents
Molecules, 2015 The first organocatalytic synthesis of cis-decalins using sulfonyl Nazarov reagents is reported. The Jørgensen’s catalyst directs this highly enantioselective synthesis using different cyclohexenal derivatives.

Advanced Science, EarlyView.Fe3S4 crystal with the exposed [001] facet exhibits higher catalytic activity for activating peroxydisulfate (PDS) to degrade clothianidin (CLO), which can be attributed to the dissolved Fe‐induced homogeneous catalytic process; while Fe3S4 crystal with the exposed [1‐21] facet exhibits excellent catalytic stability and durability, thereby boosting the

Angewandte Chemie, EarlyView.A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class

Crystal structure of (2R*,3aR*)-2-phenylsulfonyl-2,3,3a,4,5,6-hexahydropyrrolo[1,2-b]isoxazole
Acta Crystallographica Section E: Crystallographic Communications, 2017 The title compound, C12H15NO3S, was prepared by 1,3-dipolar cycloaddition of 3,4-dihydro-2H-pyrrole 1-oxide and phenyl vinyl sulfone. In the molecule, both fused five-membered rings display a twisted conformation.

Advanced Science, EarlyView.Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.

Angewandte Chemie, EarlyView.While cysteine is widely employed as a nucleophilic handle for peptide modification, the electrophilicity of the oxidized form, cystine, is rarely exploited. This study describes a mild, photochemical coupling of sulfinate salts with peptide disulfides.

Synthesis of New Active Sulfones in the 5-Nitroimidazole Series
Molecules, 2002 We describe here the preparation of new 5-nitroimidazoles which are known to have an efficacy against metronidazole-susceptible and -resistant Giarda, Trichomonas, and Entamoeba spp. The multi-step synthesis uses electron transfer methodology.
