Abstract
Disclosed is a method for producing “a salt or a complex comprising imide and an organic base”, characterized by reacting halogenated sulfuryl or halogenated phosphoryl with ammonia in the presence of an organic base. According to this method, a target imide compound can be produced in a high yield while significantly suppressing the production of by-products. Further, by reacting the obtained imide compound with an alkali metal hydroxide or an alkaline earth metal hydroxide, an imide metal salt can be easily derived.

A method for producing a salt or a complex comprising imide and an organic base represented by the formula [1]
- where R represents a halosulfonyl group (—SO2X1 where X1 is a halogen) or dihalophosphoryl group (—POX2X3 where X2 and X3 are identical or different halogens) and B represents an organic base, comprising the step of:
- reacting a dihalogenated sulfuryl (SO2X4X5 where X4 and X5 represent identical or different halogens and identical to or different from the above-mentioned X1) or halogenated phosphoryl (P(═O)X6X7X8 where X6, X7 and X8 represent identical or different halogens and identical to or different from the above-mentioned X2 or X3) with ammonia in the presence of an organic base,
- wherein the ammonia is brought into the reaction after the organic base and the dihalogenated sulfuryl or the halogenated phosphoryl are made firstly coexistent in the reaction system.
A method for producing a salt or a complex comprising imide and an organic base represented by the formula [1]
- where R represents a halosulfonyl group (—SO2X1 where X1 is a halogen) or dihalophosphoryl group (—POX2X3 where X2 and X3 are identical or different halogens) and B represents an organic base, comprising the step of:
- reacting a dihalogenated sulfuryl (SO2X4X5 where X4 and X5 represent identical or different halogens and identical to or different from the above-mentioned X1) with ammonia in the presence of an organic base,
- wherein the ammonia is brought into the reaction after the organic base and the dihalogenated sulfuryl are made firstly coexistent in the reaction system.
A method for producing an imide metal salt represented by the formula [3]
- where R represents a halosulfonyl group (—SO2X1 where X1 is a halogen) or dihalophosphoryl group (—POX2X3 where X2 and X3 are identical or different halogens) M represents an alkali metal or alkaline earth metal, and n represents an integer identical to the valence of the metal, comprising the steps of:
- (a) reacting a dihalogenated sulfuryl (SO2X4X5 where X4 and X5 represent identical or different halogens and identical to or different from the above-mentioned X1) or halogenated phosphoryl (P(═O)X6X7X8 where X6, X7 and X8 represent identical or different halogens and identical to or different from the above-mentioned X2 or X3) with ammonia in the presence of an organic base,
- wherein the ammonia is brought into the reaction after the organic base and the dihalogenated sulfuryl or the halogenated phosphoryl are made firstly coexistent in the reaction system, thereby producing a salt or a complex comprising imide and an organic base represented by the formula [1]
- where B represents the organic base;
- and
- (b) reacting the salt or the complex comprising imide and the organic base with a hydroxide or carbonate of alkali metal or a hydroxide or carbonate of alkaline earth metal.
