Abstract

The present invention provids a method for producing fluorosulfonylimides more safely, rapidly and efficiently, which enables suppression of production of by-products, and fluorosulfonylimides. The method for producing a fluorosulfonylimide salt of the present invention includes a step of reacting a fluoride compound containing at least one element selected from the group consisting of elements of Group 11 to Group 15 and Period 4 to Period 6 (excluding arsenic and antimony) with a compound represented by the following general formula (I) to give a fluorosulfonylimide salt represented by the general formula (II): [Chemical Formula 1] wherein R1 denotes at least one element selected from the group consisting of elements of Group 11 to Group 15 and Period 4 to Period 6 (excluding arsenic and antimony); R3 denotes fluorine, chlorine or a fluorinated alkyl group having 1 to 6 carbon atoms; R4 denotes fluorine or a fluorinated alkyl group having 1 to 6 carbon atoms; and m denotes an integer of 2 or 3.

Description

technical field The present invention relates to fluorosulfonyl imides, especially derivatives such as N-(fluorosulfonyl)-N-(fluoroalkylsulfonyl)imides, bis(fluorosulfonyl)imides and their salts, and their derivatives Preparation. Background technique N-(fluorosulfonyl)-N-(fluoroalkylsulfonyl)imine and bis(fluorosulfonyl)imine and their derivatives, as having N(SO 2 F) group or N(SO 2 f) 2 Intermediates of based compounds are useful; in addition, in a variety of applications (for example, as electrolytes, fuel cell electrolyte additives, selective electrophilic fluorinating agents, photoacid generators (photo acid generators), thermally induced Acid generators (thermal acid generators, and pigments that absorb near-infrared rays, etc.) are also useful compounds. The above-mentioned bis(fluorosulfonyl)imine is usually prepared by performing a halogen exchange reaction with bis(chlorosulfonyl)imine using a fluorinating agent. For example, arsenic trifluoride (ASF3) is us...
