专利号:US-2002058824-A1 优先权日:2000-11-15 标题:Solventless synthesis of hydrophilic phenol ester derivatives 发明人:MAJERCZAK VICTORIA ANN; GIBSON MICHAEL STEVEN; ORLANDO ROBERT JAMES 摘要:Process for preparing benzenesulfonate salts from an appropriately substituted acid chloride and a hydroxybenzenesulfonic acid is conducted in the absence of solvent, in a molar excess of acid chloride and in the presence of a phase transfer catalyst selected from quaternary ammonium and quaternary phosphonium salts and the target reaction product. The molar excess of the acid chloride is used to reduce the occurrence of gelation in the product.
专利号:WO-2024013736-A1 优先权日:2022-07-12 标题 :Process for preparing substituted benzamides 发明人:HAMIRANI BHAVINKUMAR; MAHESH GANDHAM; SREEDEVI MANNAM; PILLAI BIJUKUMAR GOPINATHAN 权利人:ADAMA MAKHTESHIM LTD 摘要:The present invention relates to new intermediates for the preparation of pyridylmethylbenzamides via substituted hydroxyiminopyridines or acetamidopyridines, and their innovative preparation processes. The invention discloses, in particular, the total synthesis of fluopicolide fungicide. The preparation of the main substances of the fluopicolide synthesis, specifically, substituted pyridine-2-ylmethanamine or its salt, is disclosed via two different synthesis routes, comprises two novel substances.
