Synthesis of Novel Alkyl-Sulfanyl 1,3,4-Oxadiazolyl-1,3,5,7-Tetraazatricyclic Ammonium Chloride Type Cationic Surfactants

摘要

A series of novel cationic surfactants bearing 1,3,4-oxadiazole and tetraazatricyclic ring structures were synthesized by alkyl chain elongation of 5-{10-[4-(hydroxymethyl)phenoxy]decyl}-2,3-dihydro-1,3,4-oxadiazole-2-thione with homologous series of alkyl bromides, followed by chlorination of the corresponding benzyl alcohols with thionyl chloride and quaternization of the obtained intermediates with hexamethylenetetramine.
