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

Abstract RU 2478626 C1

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method of producing N-(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 1,2-ethanedithiol, which is first mixed with aqueous formaldehyde solution at 20°C, with a hydrazide of general formula RC(O)NHNH₂ [R is as described above] in the presence of a copper chloride crystalline hydrate catalyst CuCl₂·2H₂O with molar ratio 1,2-ethanedithiol: CH₂O: RC(O)NHNH₂: CuCl₂·2H₂O = 10:20:10:(0.3-0.7), at 75-85°C and atmospheric pressure for 44-52 hours.

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