摘要：
Here, we present a synthetic strategy to access a new [1,3]thiazolo[3,2-b][1,2,4]triazolium-based cationic surfactant via the use of proton-induced heterocyclization method for quaternization of a nitrogen atom. The two-step synthesis of 2-heptyl-6,6-dimethyl-3-phenyl-5,6-dihydro-3H-[1,3]thiazolo[3,2-b][1,2,4]triazol-7-ium perchlorate is described in details. The analysis of NMR spectra unequivocally proved the formation of the 1,3-thiazolinium ring upon cyclization reaction. PM7 semiempirical calculations testify to the similar electronic structure of the newly synthesized surfactant cation and 1-heptylpyridinium cation.
