METHOD OF PRODUCING 6-ARYL-2,4,8-TRITHIA-6-AZA-1,3(1,4)-DIBENZOCYCLOOCTAPHANES Russian patent published in 2016 - IPC C07D285/00

Abstract RU 2605429 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 6-aryl-2,4,8-trithia-6-aza-1,3(1,4)-dibenzocyclooctaphanes of general formula (1)

in which N,N-bis(methoxymethyl)-N-aryl(n-methoxyphenyl, o-methoxyphenyl, o-methylphenyl)amines react with 4,4′-dimercaptophenylsulphide in presence of a samarium nitrate crystalline hydrate catalyst Sm(NO₃)₃·6H₂O, taken in molar ratio N,N-bis(methoxymethyl)-N-arylamine:4,4′-dimercaptophenylsulphide:Sm(NO₃)₃·6H₂O = 1:1:(0.03-0.07) in ethyl acetate as a solvent at room temperature (~20 °C) and atmospheric pressure for 6-8 hours.

EFFECT: production of 6-aryl-2,4,8-trithia-6-aza-1,3(1,4)-dibenzocyclooctaphanes of general formula (1) with high output.
