| titleOfInvention | METHOD FOR SELECTIVE OBTAINING 3,3 '- [BIS- (1,4-PHENYLENE)] BIS-1,5,3-Dithiazepinanes |
| abstract | The method of selective preparation of 3,3 '- [bis- (1,4-phenylene)] bis-1,5,3-dithiazepinans of the general formula (1): R = 4-CH-CH-CH-4,4-CH- O-CH-4,4-HCOCH-CHOCH-4, characterized in that diphenylenediamines (diaminodiphenylmethane, diaminodiphenyl oxide, dimethoxybenzidine) are reacted with 1-oxa-3,6-dithiacycloheptane in the presence of a Sm (NO) · 6HO catalyst in an argon atmosphere at a diphenylenediamine: 1-oxa-3,6-dithiacycloheptane molar ratio: Sm (NO) · 6HO = 1: 2: (0.03-0.07) at a temperature of ~ 20 ° C in an ethanol-chloroform solvent system for 2.5-3.5 h. |
