A Probable Origin of Dibenzothiophenes in Coals and Oils

open access: yesEnergies, 2021
To probe the possibility of thiophenolate as an origin of dibenzothiophenes (DBTs) and establish the detailed chemical transformations from thiophenolate to DBTs, the thermal degradation of thiophenolate has been carried out at various temperatures.

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Direct Conversion of Aryl Iodides Into Benzylamines by Aminomethylation: Reaction Scope, Mechanistic Studies, and Applications

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 37, 1 October 2026.
This study presents an efficient aminomethylation of aryl iodides with formamides for the synthesis of benzylamines using a reusable palladium catalyst at a loading of 65 mol ppm. The substrate scope is systematically evaluated, and mechanistic investigations provide insight into the reaction pathway and the origin of the observed catalytic efficiency.
