| Abstract: | A new method was developed for preparation of N-(1,5,3-dithiazepan-5-yl)- and N-(1,5,3-dithiazocan-5-yl)amides by transamination of N-tert-butyl-1,5,3-dithiazepane and N-tert-butyl-1,5,3-dithiazocane, and also by recyclization of 1-oxa-3,6-dithiacycloheptane and 1-oxa-3,7-dithiacyclooctane with carboxylic acids hydrazides in the presence of catalysts based on rare earth elements. |
