This work is aimed at the optimization of the yield and purity of non-symmetrical trialkyl sulfonium halide salts. The effects of parameters such as solvent, temperature and concentration were studied. The products were carefully analyzed and the crystal structure of [{n-CH3(CH2)15}(CH3)2S]Br determined. The overall aim of the present study is future syntheses of low-dimensional magnetic materials.
Graphical abstractA high-yield, one-step synthesis of sulfonium halogenides with long alkyl chains is described. A polar electrophilic solvent, trifluoroacetic acid, was used as reaction medium. Dodecyl dimethyl sulfonium, hexadecyl dimethyl sulfonium bromides and chlorides of high purity were obtained and characterized. The crystal structure of hexadecyl dimethyl sulfonium bromide has been determined.Figure optionsDownload full-size imageDownload as PowerPoint slide
