Sulfur trioxide-trimethylamine complex acts as a reagent for sulfonation and sulfamation reactions. It is used as a reactant for the synthesis of sulfate-conjugated resveratrol metabolites and chitooligosaccharides. It is used in association with dodecyl thioglycopyranoside, which acts as a surfactant for enantiomeric separation. Further, it acts as a nucleophile used for the preparation of alfa-tosyloxy ketones.
1-Ethyl-3-methyl-1H-imidazol-3-ium tetrachloroferrate(III) serves as a stable, bench-ready ionic liquid catalyst for electrophilic functionalization reactions. Its imidazolium cation enables efficient activation of substrates in Friedel–Crafts-type processes, while the tetrachloroferrate(III) anion provides strong Lewis acidity under mild conditions. The salt exhibits excellent functional group tolerance and facilitates clean reaction profiles with straightforward purification, making it well-suited for scalable synthesis of complex heterocycles and aromatic derivatives.
