FIELD: chemistry.SUBSTANCE: invention refers to organic chemistry, more specifically to a method for preparing N-(1,5,3-dithiazocynan-3-yl)amides of formula, wherein R=p-CHN (a), (CH)CO (b), o-CHOCH(c), which can find application as biologically active compounds, selective sorbents and precious metal extractants. Substance of the method consists in the reaction of N,N,N,N- tetramethyl-2,5-dithiaheptane-1,7-diamine with hydrazides RC(O)NHNHin the presence of the catalyst samaric nitrate crystallohydrate Sm(NO)·6HO at temperature 65-75°C for 20-26 h.EFFECT: what is developed is a method for preparing new high-selectivity N-(1,5,3-dithiazocynan-3-yl)amides.1 cl, 1 tbl, 1 ex |
