| Zusammenfassung: | There is provided a method for the preparation of a 2-perfluoroalkyl-3-oxazolin-5-one compound of formula (II) comprising reacting an aminonitrile with a perfluoroacylating agent in the presence of a solvent to form a perfluoroalkanoyl aminonitrile intermediate and cyclizing the intermediate in the presence of an acid and at least one molar equivalent of water. Perfluoro-alkanoyl aminonitrile intermediates are also claimed. wherein n is an integer of 1,2,3,4,5,6,7 or 8; L is hydrogen or halogen.r |
