FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing hexaoxathiodyspiral alkanes and involves reacting heptaoxadispiroalkanes [6,7,13,14,16,18,19-heptaoxadispiro[4.2.48.75]nonadecane or 3,12-dimethyl-7,8,15,16,18,20,21-heptaoxadispiro[5.2.59.76] or henicosan 8,9,17,18,20,22,23-heptaoxadispiro [6.2.610.77] trikozan]) with hydrogen sulphide in the presence of a catalyst TbCl3⋅6H2O at room temperature and atmospheric pressure for 4–6 hours.
EFFECT: output of 3 hexaoxathiodyspiral alkanes (1) is equal to 79–87 %.
