METHOD OF OBTAINING N-(1,5,3-DITHIAZONAN-3-YL)AMIDES Russian patent published in 2014 - IPC C07D417/12 C07D285/00

Abstract RU 2516696 C1

FIELD: chemistry.

SUBSTANCE: invention relates to field of organic chemistry, namely, to method of obtaining N-(1,5,3-dithiazonan-3-yl)amides of general formula (1) where R=p-C₅H₄N (a), (CH₃)₃CO (b), m-C₅H₄N (c), which consists in the fact, that N¹,N¹,N⁸,N⁸-tetramethyl-2.7-dithiaoctane-1.8-diamine is subjected to interaction with hydrazide of general formula RC(O)NHNH₂ [R=upper said] in presence of catalyst samarium nitrate crystalhydrate Sm(NO₃)₃·6H₂O, at molar ratio N¹,N¹,N⁸,N⁸-tetramethyl-2.7-dithiaoctane-1.8-diamine: RC(O)NHNH₂: Sm(NO₃)₃·6H₂O = 10 : 10 : (0.3-0.7) at temperature 75-85°C and atmospheric pressure in mixture of solvents ethyl alcohol-chloroform for 20-28 h.

EFFECT: method of obtaining novel compounds, which can be applied as biologically active compounds, selective sorbents and extractants of noble and precious metals, is developed.
