Abstract
To provide an imide salt represented by the formula wherein, R represents a halosulfonyl group (—SO2X1 where X1 is a halogen such as fluorine, chlorine, bromine and iodine) or dihalophosphoryl group (—POX2X3 where X2 and X3 are the same or different halogens such as fluorine, chlorine, bromine and iodine), and M represents an alkali metal; with high selectivity and high efficiency by using a low-cost starting material. In the production of an imide salt, an alkali metal fluoride, a sulfuryl halide or phosphoryl halide, and ammonia or an ammonium salt are reacted. According to this method, a desired imide salt can be produced with high yield, while greatly suppressing the production of a by-product.
Claims4
A method for producing an imide salt represented by formula [1]
- wherein, R represents a halosulfonyl group (—SO2X1 where X1 is a halogen selected form the group consisting of fluorine, chlorine, bromine and iodine) or dihalophosphoryl group (—POX2X3 where X2 and X3 are the same or different halogens selected form the group consisting of fluorine, chlorine, bromine and iodine), and M represents an alkali metal, comprising the step of:
- reacting an alkali metal fluoride, a sulfuryl dihalide (SO2X4X5 where X4 and X5 represent the same or different halogens selected form the group consisting of fluorine, chlorine, bromine and iodine, and are the same as or different from the above-mentioned X1) or phosphoryl halide (P(═O)X6X7X8 where X6, X7 and X8 represent the same or different halogens selected form the group consisting of fluorine, chlorine, bromine and iodine, and are the same as or different from the above-mentioned X2 or X3), and ammonia or an ammonium salt,
- wherein the alkali metal fluoride and the sulfuryl dihalide or phosphoryl halide are made coexistent in the reaction system firstly, followed by bringing ammonia or the ammonium salt into the reaction.
