专利号:US-5206392-A 优先权日:1992-04-27 标 题:Facile synthesis of arylmaleic acids and anhydrides 发明人:DEAN WILLIAM D 权利人:AMERICAN CYANAMID CO 摘要:A process for making acrylmaleic acid and arylmaleic anhydride derivative useful as intermediates for the preparation of arylmaleimides in the synthesis of compounds having activity in the central nervous system. The process involves reacting arylacetonitriles with glyoxylic acid to provide novel intermediate 3-aryl-3-cyanopropeneoates which may be converted to the arylmaleic acid and arylmaleic anhydride derivatives.
专利号:US-2004024238-A1 优先权日:1999-07-02 标 题:Use of nitriles as polar aprotic solvents 发明人:LAURAIN NATHALIE; ZARD SAMIR 摘要:The invention concerns the use of aliphatic nitriles with relatively high molecular weight, as polar aprotic solvents, in particular in nucleophilic substitution reactions of the aromatic type. Said nitriles have a molecular mass more 79, preferably more than 90. The invention is useful for synthesis of fluorinated aromatic compounds.
专利号:US-4219684-A 优先权日:1979-04-02 标 题 :Synthesis of alcohols by hydroformylation with nitrile promoter 发明人:IMAI TAMOTSU 权利人:UOP INC 摘要:Alcohols may be synthesized by reacting an olefinic compound, carbon monoxide and hydrogen in the presence of a Group VIII organometallic complex catalyst at reaction conditions which include a temperature in the range of from about 50° to about 250° C. and a pressure in the range of from about 10 to about 300 atmospheres. In addition, the reaction is also effected in the presence of a promoter compound comprising a nitrile.
