METHODS FOR PRODUCING BIS(SULFONYL)IMIDE AMMONIUM SALT, BIS(SULFONYL)IMIDE AND BIS(SULFONYL)IMIDE LITHIUM SALT

摘要

To provide methods for producing a bis(sulfonyl)imide ammonium salt, a bis(sulfonyl)imide and a bis(sulfonyl)imide lithium salt simply and in good yield. A method for producing a bis(sulfonyl)imide ammonium salt, which comprises reacting a compound of the formula R—CHF—SO2X (wherein R is a C1-4 fluorinated alkyl group which may contain an etheric oxygen atom, or a fluorine atom, and X is a fluorine atom or a chlorine atom) with ammonia in the absence of a catalyst. Further, methods for producing a bis(sulfonyl)imide and a bis(sulfonyl)imide lithium salt by using the bis(sulfonyl)imide ammonium salt.
