FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining 1,6-bis-(1,5,3-dithiazepan-3-yl)-2,5-disulphanylhexane of formula (1), possessing fungicidal activity against Botrytis cinerea and Rhizoctonia solani. Essence of method lies in interaction of mixture of 1,2-ethanedithiol and formaldehyde with water solution of ammonium salts NH4X (X=F, Br, OAc, NO3, 1/2SO4) with molar ratio HS(CH2)2SH:CH2O:NH4X=3:6:2 at room temperature (~20°C) and atmospheric pressure for 5-7 h.
EFFECT: output of 1,6-bis-(1,5,3-dithiazepan-3-yl)-2,5-disulphanylhexane of general formula (1) depending on applied ammonium salts (NH4X) constitutes 31-67%.
