METHOD FOR PRODUCING IMIDE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fluorinated imide compound, which uses inexpensive starting materials and is highly safe and highly productive.SOLUTION: A method for producing an imide compound ((RfSO)(RfSO)NH) by making a perfluoroalkyl sulfonic acid (RfSOH) react with a perfluoroalkyl sulfonamide (RfSONH) in the presence of sulfur trioxide is selected, wherein each of Rfand Rfrepresents fluorine or a linear or branched 1-4C perfluoroalkyl group.
