N‐(Heptafluoroisopropylthio)saccharin as a Practical Reagent for Electrophilic –SCF(CF3)2 Installation

Advanced Synthesis &Catalysis, Volume 368, Issue 3, 3 February 2026.
A bench‐stable saccharin electrophilic reagent enables the direct installation of the heptafluoroisopropylthio group onto diverse (hetero)arenes and amines under mild conditions. The method forms CSRF and NSRF bonds in a single step and allows subsequent oxidation to sulfonamides.

Structural basis for the oxidation of protein-bound sulfur by the sulfur cycle molybdohemo-enzyme sulfane dehydrogenase SoxCD

, 2010
The sulfur cycle enzyme sulfane dehydrogenase SoxCD is an essential component of the sulfur oxidation (Sox) enzyme system of Paracoccus pantotrophus. SoxCD catalyzes a six-electron oxidation reaction within the Sox cycle.

Supersulfide biology and translational medicine for disease control

British Journal of Pharmacology, Volume 183, Issue 1, Page 115-130, January 2026.
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Thioether Synthesis via the Nickel‐Catalyzed Electrochemical Cross Electrophile Coupling of Aryl/Alkyl Disulfides and Aryl/Alkyl Halides

Advanced Synthesis &Catalysis, Volume 367, Issue 22, November 28, 2025.
A nickel catalyzed electrochemical cross‐electrophile coupling approach for the base‐free synthesis of (un)symmetric (hetero)aryl and alkyl sulfides from organic halides and disulfides is described. The reaction is broadly applicable and tolerates water and air atmosphere. A formal cross‐electrophile coupling approach enables the base‐free synthesis of

Data_Sheet_1_Escherichia coli Uses Separate Enzymes to Produce H2S and Reactive Sulfane Sulfur From L-cysteine.pdf

, 2019
Hydrogen sulfide (H2S) has been proposed to have various physiological functions, and it may function through reactive sulfane sulfur. Since the two sulfur forms often coexist, they are normally considered interchangeable.

Possible Involvement of Hydrosulfide in B12-Dependent Methyl Group Transfer

Molecules, 2017
Evidence from several fields of investigation lead to the hypothesis that the sulfur atom is involved in vitamin B12-dependent methyl group transfer. To compile the evidence, it is necessary to briefly review the following fields: methylation, the new ...

Benzothiazole-Derived Sulfones and Sulfoxides as Reactive Templates for Biothiols and Sulfane Sulfurs

, 2022
In this work we studied the reactions of benzothiazole sulfones and sulfoxides toward reactive sulfur species. The reaction of thiols with benzothiazole sulfones produces sulfinic acids (RSO2H), which can further react with sulfane sulfurs to form ...

Imaging and evaluation of sulfane sulfur in acute brain ischemia using a mitochondria-targeted near-infrared fluorescent probe

, 2018
Ischemia is a pathological condition owing to the deficiency of blood supply to a limited area of tissue. Ischemia can induce burst production of reactive oxygen species and lead to oxidative damage. As a family member of reactive sulfur species, sulfane

Human Sulfide:Quinone Oxidoreductase Catalyzes the First Step in Hydrogen Sulfide Metabolism and Produces a Sulfane Sulfur Metabolite

, 2016
Sulfide:quinone oxidoreductase (SQOR) is a membrane-bound enzyme that catalyzes the first step in the mitochondrial metabolism of H2S. Human SQOR is successfully expressed at low temperature in Escherichia coli by using an optimized synthetic gene and ...
