摘要:
A one pot process for the perfluoroalkylation and/or perfluoroacyloxylation of organic substrates is provided. The process comprises contacting a substrate with a perfluoroalkanoic anhydride in the presence of a an inorganic peroxygen compound at a temperature of greater than 10°C. Substrates that can be perfluoroalkylated and/or perfluoroacyloxylated include alkylbenzenes, halogenated aromatic compounds, alkoxybenzenes, aryl benzenes, and aromatic and aliphatic disulphides. Preferably, the perfluoroalkanoic anhydride is trifluoroacetic anhydride and the inorganic peroxygen compound is sodium percarbonate.
摘要:
6,6'-terephthal-di(amidoperoxyhexanoic) acid is a new peroxyacid compound. It can be prepared by peroxidation of 6,6'-terephthal-di(amidohexanoic) acid. Conveniently, the peroxidation is achieved employing a solution of 6,6'-terephthal-di(amidohexanoic) acid in sulphuric acid solution reacted with a solution of Caro's acid, the concentration of sulphuric acid in the reaction mixture being chosen such that the 6,6'-terephthal-di(amidoperoxyhexanoic) acid is insoluble in the reaction mixture, but that the 6,6'-terephthal-di(amidohexanoic) acid is soluble therein.
