METHOD FOR SELECTIVE PRODUCTION OF 3,3'-[BIS-(1,4-PHENYLENE)]BIS-1,5,3-DITHIAZEPINANES Russian patent published in 2014 - IPC C07D417/10 C07D417/12

Abstract RU 2529506 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method for selective production of 3,3'-[bis-(1,4-phenylene)]bis-1,5,3-dithiazepinanes of formula (1) where R = 4-C₆H₄-CH₂-C₆H₄-4', 4-C₆H₄-O-C₆H₄-4', 4-H₃COC₆H₃-C₆H₃OCH₃-4', where diphenylenediamines (diaminodiphenylmethane, diaminodiphenyl oxide, dimethoxybenzidine) react with 1-oxa-3,6-dithiacycloheptane in the presence of a Sm(NO₃)₃·6H₂O catalyst in an argon atmosphere in molar ratio diphenylenediamine:1-oxa-3,6-dithiacycloheptane:Sm(NO₃)₃·6H₂O=1:2:(0.03-0.07) at about 20°C in an ethanol-chloroform solvent system for 2.5-3.5 hours.

EFFECT: novel method of producing 3,3'-[bis-(1,4-phenylene)]bis-1,5,3-dithiazepinanes, which can be used as antimicrobial, antifungal and anti-inflammatory agents, sorbents and extractants of precious metals and selective complexing agents.
