1460559 Aromatic and heteroaromatic sulphides and disulphides IRKUT INST ORGANICHE KHIMII SIBIR OTDELEN AKAD NAUK SSSR 1 May 1975 18126/75 Heading C2C Aromatic or heteroaromatic sulphides and/or disulphides are prepared by reacting chlorine or bromine derivatives of aromatic or heteroaromatic compounds with H 2 S at 150-700‹ C. Preferably chlorine derivatives are reacted in gaseous phase in recirculating flow at 400-600‹ C. and bromine derivatives in inert organic solvent at 20-300‹ C. Examples prepare diphenyl sulphide, di(4 - methylphenyl)sulphide, di- (2 - thienyl sulphide), di(5-methyl-2-thienyl)- sulphide, di(5 - chloro - 2 - thienyl)sulphide, diphenyl disulphide, di(2 - thienyl)disulphide, di( 1-naphthyl)sulphide, di(o-phenanthryl)sulphide and di(9-anthryl)sulphide. Mercaptan by-products are obtained in some cases. |
