摘要：
2,3-Dihydrothiazolo[2,3-b]thiazolium iodides and bromide have been obtained for the first time via cyclization of the corresponding methallyl- and propinylsulfanyl derivatives of 1,3-thiazole with iodine and bromine in dichloromethane without heating and the use of strong acids. The structure of the obtained compounds has been studied by means of H-1 and C-13{H-1} NMR spectroscopy. Structure of the 3-iodomethyl-3,5-dimethyl-2,3-dihydrothiazolo[2,3-b][1,3]thiazolium heterocyclic system and the cation-anion noncovalent interactions have been analyzed on the basis of quantum-chemical simulations with periodic boundary conditions and characterized by means of X-ray diffraction analysis.
