FIELD: chemistry.SUBSTANCE: invention relates to field of synthesis of compounds with biological activity, namely to method of obtaining compound 3,3'-(3,6-dioxaoctane-1,8-diyl)bis-1,5,3-dithiazepinane. Essence of method consists in interaction of 3,6-dioxaoctane-1,8-diamine with N,N,N,N-tetramethyl-2,5-dithiahexane-1,6-diamine in medium ethanol-chloroform (1:2 volume) in presence of catalyst SmCl·6HO with molar ratio 3,6-dioxaoctane-1,8-diamine:N,N,N,N-tetramethyl-2,5-dithiahexane-1,6-diamine:SmCl·6HO=1:2:(0.03-0.07) at temperature (~20°C) and atmospheric pressure for 2.5-3.5 h. Invention also relates to application of 3,3'-(3,6-dioxaoctane-1,8-diyl)bis-1,5,3-dithiazepinane as agent with fungicidal activity for fighting fungal diseases of agricultural crops.EFFECT: improved method of obtaining 3,3'-(3,6-dioxaoctane-1,8-diyl)bis-1,5,3-dithiazepinane, possessing fungicidal activity against Botrytis cinerea.2 cl, 2 tbl, 1 ex |
