METHOD OF PRODUCING 1,2,4,5-TETRAKIS(4-R-PHENYLSULFANYL)BENZENES

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for synthesis of tetrasubstituted benzenes; , where R = Cl, H. Method involves a process of reacting 1,5-dichloro-2,4-dinitrobenzene with thiophenol or derivatives thereof in DMFA in the presence of K₂CO₃ at temperature of 140 °C for 2 hours in a molar ratio of 1,5-dichloro-2,4-dinitrobenzene : 4-R-thiophenol = 1:4.;EFFECT: method enables production of products with high output (95–97 %) over a shorter period of time and is more economical due to exclusion of expensive agents.;1 cl, 2 ex
