METHOD OF PRODUCING N-(1,5,3-DITHIAZEPAN-3-YL)AMIDES Russian patent published in 2013 - IPC C07D285/36 C07D417/12

Abstract RU 2482114 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to organic chemistry and specifically to a method of producing M-(1,5,3-dithiazepan-3-yl)amides of general formula (1) where R = p-C₅H₄N (a), (CH₃)₃CO (b), o-CH₃OC₆H₄ (c), which involves reaction of N¹,N¹,N⁶,N⁶-tetramethyl-2,5-dithiahexane-1,6-diamine with a hydrazide of general formula RC(O)NHNH₂ [R is as described above] in the presence of a samarium nitrate crystalline hydrate Sm(NO₃)₃·6H₂O catalyst with molar ratio N¹,N¹,N⁶,N⁶-tetramethyl-2,5-dithiahexane-1,6-diamine:RC(O)NHNH₂:Sm(NO₃)₃·6H₂O=10:10:(0.3-0.7) at temperature of 65-75°C and atmospheric pressure in the mixture of solvents - ethyl alcohol and chloroform for 20-28 hours.

EFFECT: method of producing N-(1,5,3-dithiazepan-3-yl)amides with high selectivity and output, which can be used as biologically active compounds, selective sorbents and extractants of noble and precious metals.
