Method for Producing Lithium Sulfamate and New Lithium Sulfamate

摘要

Provided is a method for producing a lithium sulfamate. The method for producing a lithium sulfamate includes (1) reacting a compound (1) represented by the following formula (1):wherein X is fluorine, chlorine, bromine, or iodine, with a compound (2) represented by the following formula (2) :wherein R1 and R2 are each individually a substituent that is:-H;a group represented by the formula: -Op-(SiR32O)n-SiR43 wherein R3 and R4 are each individually an alkyl group in which at least one hydrogen atom is optionally replaced with a fluorine atom, an alkenyl group in which at least one hydrogen atom is optionally replaced with a fluorine atom, an alkynyl group in which at least one hydrogen atom is optionally replaced with a fluorine atom, or an aryl group in which at least one hydrogen atom is optionally replaced with a fluorine atom; n is an integer of 0 or greater; and p is 0 or 1;a C1-C7 alkyl group;a C2-C7 alkenyl group;a C2-C7 alkynyl group;a C6-C15 aryl group;-SO2X1 wherein X1 is -H, -F, or an alkyl group in which at least one hydrogen atom is optionally replaced with a fluorine atom;-SO3X2 wherein X2 is -H, -F, or an alkyl group in which at least one hydrogen atom is optionally replaced with a fluorine atom; ora C2-C7 hydrocarbon group that forms a cyclic structure by bonding of R1 and R2, in which the cyclic structure optionally contains a multiple bond,the substituent optionally containing at least one bi- to hexavalent heteroatom in the structure and being a substituent in which at least one hydrogen atom is optionally replaced with a fluorine atom or a CO-C7 functional group, to obtain a compound (3) represented by the following formula (3):wherein R1 and R2 are defined as above.
