Organothiocyanate and organoselenocyanate compounds are of paramount importance in organic chemistry as they key intermediates to access sulfur- selenium-containing compounds. Therefore, among the different synthetic pathways get SCN- SeCN-containing molecules, original methodologies using electrophilic reagents have recently been explored. This Minireview will showcase recent advances that mad...

Sulfur compounds adversely affect the technological process of oil and gas refining, as well release sulfur-containing into atmosphere, polluting environment. Oil processing is carried out using microporous adsorbents with high sorption capacity in purification gases containing sulfur. This one most efficient methods refining processing. In research work, adsorption sulfur their composition var...

Sulfur is an essential nutrient, necessary for synthesis of many metabolites. The uptake of sulfate, primary and secondary assimilation, the biosynthesis, storage, and final utilization of sulfur (S) containing compounds requires a lot of movement between organs, cells, and organelles. Efficient transport systems of S-containing compounds across the internal barriers or the plasma membrane and ...

A dibenzothiophene (DBT)-desulfurizing bacterial strain was isolated and identified as Gordona strain CYKS1. Strain CYKS1 was found to transform DBT to 2-hydroxybiphenyl via the 4S pathway and to be able to also use organic sulfur compounds other than DBT as a sole sulfur source. Its desulfurization activity was susceptible to sulfate repression. Active resting cells for desulfurization could b...

Currently, Euro 5 (no more than 10 ppm sulfur content) and 6 (less diesel motor fuels are produced worldwide. High-quality by removing compounds using a hydrodesulfurization process. This article is devoted to the study of fuel containing 120 in presence an Al-Ni-Mo-O catalyst with 98% purification rate. According Langmuir–Hinshelwood–Panchenkov theory, kinetic model process developed calculati...

A large variety of unique heterocyclic natural marine products, without terrestrial counterparts, have been isolated from marine invertebrates, mainly sponges, ascidians, and soft corals. Many of these compounds display interesting biological activity. In this review, we report our recent studies on nitrogen-containing heterocyclic compounds (“alkaloids”), as well as some containing sulfur and ...

We report a 67Zn nuclear magnetic resonance (NMR) study of compounds containing zinc ions coordinated by oxygen, nitrogen, and sulfur ligands. New information concerning 67Zn nuclear quadrupole coupling constants (NQCC) and chemical shift was obtained from magic-angle spinning (MAS) spectra of solid compounds containing both natural abundance and enriched 67Zn isotopes. Rapid ligand exchange pr...
