Reactions of a series of ω-halocarboxylic acids (2-bromo-, 2-chloroethanoic, 3-bromo- and 3-chloropropanoic) with dimethyl sulfide resulted in the formation of stable (carboxylalkyl)dimethylsulfonium bromides and chlorides. Composition and structure of the salts obtained were established by a complex of chemical, physical and physicochemical methods. The sulfonium salts obtained showed high antibacterial

The fixed charge zwitterionic sulfur betaines dimethylsulfonioacetate (DMSA) (CH3)2S+CH2CO2− and dimethylsulfoniopropionate (DMSP) (CH3)2S+(CH2)2CO2− have been synthesized and the structures of their protonated salts (CH3)2S+CH2CO2H⋯Cl− [DMSA.HCl] and (CH3)2S+(CH2)2CO2H⋯Pcr− [DMSP.HPcr] (where Pcr = picrate) have been characterized using X-ray crystallography. The unimolecular chemistry of the [M+H]+
