标 题 :Synthesis of alkoxy and phenoxy substituted aryl sulfides
发明人：HANSON HARRY T; SAPP JR JOHN B
权利人:CELANESE CORP
摘要:Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.

摘要:A method is directed to synthesis of poly(triphenylacrylonitrite)s (PTPANs) comprising polycoupling dibromoarenes, internal diynes, and potassium ferrocyanide, resulting in polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide; and producing poly(triphenylacrylonitrite)s (PTPANs) by catalysis of the polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide with palladium acetate and sodium bicarbonate, wherein the catalysis is allowed to proceed in dimethylacetamide under nitrogen at a prescribed temperature for a prescribed time. Further, poly(triphenylacrylonitrite)s (PTPANs) is a polymer and comprises a backbone structure of n nwherein x and y are integers;n nwherein each R is independently selected from the group consisting ofn n nandn nwherein each R′ is independently selected from the group consisting of

权利人:UNIV LANZHOU; THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING / MCGILL UNIV
摘要:It is provided a method of converting a diaryl ether source such as lignin and/or polyphenylene oxide (PPO) containing 4-O-5 linkages and an inorganic chemical such as ammonia into an organic compound, comprising reacting said diaryl ether source with the inorganic chemical in presence of a catalyst, preferably palladium, transforming the 4-O-5 linkages of said diaryl ether source into the organic compound. It is provided a palladium-catalyzed synthesis of aniline derivatives from 4-O-5 linkage lignin model compounds and cheap industrial inorganic chemical ammonia via dual C(Ar)—O bond cleavage.
