Environmental Science & Technology, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 19, 2024

The recently proposed partial denitrification (PD), terminating nitrate reduction to nitrite, has been regarded as a promising alternative nitrite supplying for anammox bacteria. most important aspect of the PD process engineering application is stable and continuous supply nitrite. However, activity reductase often higher than that (NIR), making it difficult accumulate during process. Herein, strategy achieving efficient using biosafe additive dimethyl sulfoxide (DMSO) was constructed, mechanism DMSO inhibiting NIR analyzed. addition reduced expression gene, 1% can significantly inhibit enzyme achieve When concentration increased 3.5%, almost inhibited with only 0.95 mg nitrite/min. no inhibitory effect on (NAR) enzyme. affinity constant NAR −2.4 kcal/mol, while high −3.1 kcal/mol. shows NIR. Moreover, occupy same catalytic cavity in enzyme, which fundamental reason why selectively inhibits This study provides new idea realizing function.

Transition-metal-free C–S bond cleavage and transformation of organosulfur compounds

Chemical Communications, Год журнала: 2023, Номер 59(36), С. 5343 - 5364

Опубликована: Янв. 1, 2023

The activation and transformation of organic chemical bonds is a fundamental scientific problem. In the past several decades, C-S bond cleavage for construction C-C C-heteroatom has received tremendous attention in chemistry. Although significant progress been made field transition metal strategies, variety novel transition-metal-free strategies have also developed using halogenated reagents, oxidants, acids, bases. Moreover, photochemical electrochemical methods to achieve organosulfur compounds. To date, however, no comprehensive review reported. Therefore, we herein provide major advances compounds, including thioethers, sulfoxides, sulfones, thioacetals, sulfonium salts, sulfur ylides.

Electrochemical N–H Methylsulfoxidation of Sulfoximines with DMSO

Chinese Journal of Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

Comprehensive Summary The N–H methylsulfoxidation of sulfoximines using DMSO as a methylsulfinyl source, induced by electrochemistry, has been developed. This method is the first example an electrochemical reaction in which serves source. Unlike previous reactions involving substrate, exclusively proceed via radical mechanisms, this follows S‐cation pathway. A wide range N ‐methylsulfinyl were successfully obtained.

TCT-Mediated and Water-Controlled Synthesis of Benzofuran-3(2H)-ones Bearing a Quaternary Carbon Center via a Radical Process Using Dimethyl Sulfoxide as a Dual Synthon

The Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Апрель 10, 2025

An efficient and attractive method for the synthesis of valuable benzofuran-3(2H)-one derivatives bearing a quaternary center in one step by employing dimethyl sulfoxide (DMSO) as dual synthon under metal-free conditions has been developed. In this reaction, DMSO activated cyanuric chloride (TCT) provides two different units (CH3 SMe) target molecules, construction carbon benzofuran-3(2H)-ones can be controlled addition water. Furthermore, functional group compatibility synthetic value were demonstrated scope evaluation gram-scale experiments. The mechanistic studies show that reaction may proceed via radical process.
