FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing 1,4,7(8,9)-trithia-2,9(10,11)-diazacycloalkane 1,1-dioxides of general formula (1), which consists in the fact that sulfamide is subjected to interaction with paraform and α,ω-dithiols selected from the range of 1,2-ethane-, or 1,3-propane-, or 1,4-butanedithiol, in the presence of Sm(NO3)3⋅6H2O as a catalyst, taken in the molar ratio of sulfamide: paraform: α,ω-dithiol:[Sm(NO3)3⋅6H2O]=10:(15-25):10:(1-3), at a temperature of 60-80°C for 6.5-7.5 h in a mixture of solvents chloroform:ethanol=1:1. The method makes it possible to prepare compounds of formula (1) with a yield of 31-70%.
EFFECT: obtaining 1,4,7(8,9)-trithia-2,9(10,11)-diazacycloalkane 1,1-dioxides of the general formula (1).
