Summary: Biomass burning releases phenols that can form aqueous secondary organic aerosol (aqSOA) in cloud/fog drops and aerosol liquid water (ALW). Highly substituted phenols have significant partitioning and oxidation kinetics in ALW, potentially being important sources of aqSOA. The formation of aqSOA is significant across a range of liquid water content.

Summary: Thirty-three alkyl and aryl isothiocyanates, as well as their derivatives, were successfully synthesized with satisfactory yields using a one-pot, two-step procedure in the presence of organic base and carbon disulfide. The antibacterial activity of these compounds was evaluated, with ITC 9e showing the highest activity against E. coli and S. aureus bacterial strains.

Summary: Supported ionic liquids (SILs), immobilized ILs onto solid support materials, have shown advantages over pure ILs in various applications. In this study, new SILs were synthesized by immobilizing S-alkyl/aryl-substituted 2-mercaptobenzothiazolium-based ILs onto MCM-41 silica support. The synthesized SILs were characterized, and their performance in removing sulfur-containing aromatic species from gasoline was investigated. MCM-41@[S-BzBTh][Cl] showed excellent sulfur removal efficiency from model gasoline.

Summary: We present a metal- and additive-free method for synthesizing meta-substituted anilines using commercially available or one-step accessible substituted methylvinyl ketones, N-acylpyridinium salts, and primary/secondary alkyl- and arylamines. This method enables the synthesis of anilines with uncommon substitution patterns and has potential applications in medicinal chemistry and materials science.
