METHOD OF SELECTIVE OBTAINING 3,3'-[METHYLENEBIS(1,4-PHENYLENE)]-, 3,3'-[OXYBIS(1,4-PHENYLENE)]- AND 3,3'-(3,3'-DIMETHOXYBIPHENYL-4, 4'-DIYL)-BIS-1,5,3-DITHIAZEPINANES Russian patent published in 2014 - IPC C07D417/12 C07D417/10

Abstract RU 2518485 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry, namely to method of obtaining 3,3'-[methylenebis(1,4-phenylene)]-, 3,3'-[oxybis(1,4-phenylene)]- and 3,3'-(3,3'-dimethoxybiphenyl-4, 4'-diyl)-bis-1,5,3-dithiazepinanes of general formula (1): R=4-C₆H₄-CH₂-C₆H₄-4/, 4-C₆H₄-O-C₆H₄-4/, 4-H₃COC₆H₃-C₆H₃OCH₃-4/ which consists in the following: arylamines [diaminodiphenylmethane, diaminodiphenyloxide, dimethoxybenzidine] undergo interaction with N-tert-butyl-1,5,3-dithiazepinane in presence of catalyst Sm(NO₃)₃·6H₂O in argon atmosphere with molar ratio arylamine:N-tert-butyl-1,5,3-dithiazeoinane: Sm(NO₃)₃·6H₂O = 10 : 20 : (0.3-0.7) at temperature ~20°C in system of solvents ethanol-chloroform for 2.5-3.5 h.

EFFECT: increased efficiency of applying compound as antibacterial, antifungal and antiviral agents, biologically active complexants, selective sorbents and extractants of precious metals, special reagents for suppressing bacterial vital activity in different technical media.
