METHOD OF PRODUCING MONO-(DI-, TETRA-)METHYL-1,2-BIS-(1,3,5-DITHIAZINAN-5-YL)ETHANES Russian patent published in 2012 - IPC C07D417/06

Abstract RU 2443702 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing mono-(di-, tetra-)methyl-1,2-bis-(1,3,5-dithiazinan-5-yl)ethanes of general formula (1-3): , (1) R₁=CH₃, R₂, R₃, R₄=H (2) R₁, R₃=CH₃, R₂, R₄=H (3) R₁, R₂, R₃, R₄=CH₃, which involves reaction of hydrogen sulphide-saturated aqueous solution of (37%) formaldehyde and acetaldehyde with 1,2-diaminoethane with molar ratio of initial reagents 1,2-diaminoethane: formaldehyde: acetaldehyde: hydrogen sulphide equal to 10:50:10:40 to obtain (1), 10:40:20:40 to obtain (2), 10:20:40:40 to obtain (3), at temperature 40°C and atmospheric pressure for 2.5-3.5 hours.

EFFECT: method of obtaining novel compounds which can be used as selective sorbents and extraction agents of precious metals, agents for protecting leather, fur and textile from biodeterioration, biologically active substances with respect to different microorganisms and sulphate-reducing bacteria.
