Synthesis of N-aryl-1,5,3-dithiazepanes and N-aryl-1,5,3-dithiazocanes in the presence of samarium- and cobalt-containing catalysts
摘要:
Efficient procedures were developed for the synthesis of N-aryl-1,5,3-dithiazepanes and N-aryl-1,5,3-dithiazocanes by cyclocondensation of anilines with formaldehyde and alpha,omega-dithiols (etane-1,2-dithiol and propane-1,3-dithiol), as well as by transamination of N-tert-butyl-1,5,3-dithiazepane or N-tert-butyl-1,5,3-dithiazocane with aromatic amines in the presence of samarium and cobalt complexes.

New derivatives of 1,5,3-dithiazepanes and macroheterocycles were synthesized by a three-component cyclothiomethylation of arylamines with formaldehyde and alpha,omega-dithiols. The sorption properties of 3-phenyl-1,5,3-dithiazepane and 6-phenyl-1,11-dioxa-4,8-dithia-6-azacyclotridecane applicable for the extraction of Ag(I) and Pd(II) ions from nitric acid solutions at room temperature were studied by a static method.
