Method for producing an imide acid compound

PROBLEM TO BE SOLVED: To produce "a salt or a complex comprising imidic acid and an organic base" expressed by chemical formula, wherein R denotes a halosulfonyl group (-SO 2 X 1 ; X 1 is halogen (fluorine, chlorine, bromine and iodine) or a dihalophosphoryl group (-POX 2 X 3 ; X 2 , X 3 are halogen (fluorine, chlorine, bromine and iodine) and may be different or may be the same) and B denotes an organic base), with high selectivity and high efficiency by using inexpensive raw materials. SOLUTION: The method for producing "the salt or the complex comprising imidic acid and the organic base" is characterized by reacting halogenated sulfuryl or halogenated phosphoryl with ammonia in the presence of an organic base. According to this method, a target imidic acid compound can be produced in a high yield while significantly suppressing the production of by-products. Further an imidic acid metal salt can be easily derived by reacting the obtained imidic acid compound with an alkali metal hydroxide or an alkaline earth metal hydroxide. COPYRIGHT: (C)2011,JPO&INPIT
