METHOD OF PRODUCING 1,6-BIS-[ALKYL(ARYL)SULPHONYLAMINO]-2,5-DITHIAHEXANE Russian patent published in 2024 - IPC C07C319/08 C07C321/14 C07C321/16

Abstract RU 2821791 C1

FIELD: organic chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method of producing 1,6-bis-[alkyl(aryl)sulphonylamino]-2,5-dithiahexane of general formula (1). Method involves reaction of alkyl(aryl)sulphamides, namely methylsulphamide, benzylsulphamide or tolylsulphamide with 1,6-bis-(hydroxy-2,5-dithio)hexane in the presence of Sm(NO₃)₃⋅6H₂O as a catalyst, taken in molar ratio sulphamide:1,6-bis-(hydroxy-2,5-dithio)hexane:[Sm(NO₃)₃⋅6H₂O] = (1.5÷2.5):1:(0.05÷0.15) at temperature 50÷70 °C for 9–15 hours in a mixture of solvents EtOH:CHCl₃ (2:1, vol).

EFFECT: obtaining 1,6-bis-[alkyl(aryl)sulphonylamino]-2,5-dithiahexane, which can be used as catalysts, as well as used for targeted drug delivery.
