Abstract
A bis(trifluoromethanesulfonyl)ethyl group-bearing compound represented by the following formula [1], [2] or [3] .
Claims2
A method for producing a bis(trifluoromethanesulfonyl)ethyl group-bearing compound represented by formula [1], characterized by causing 1,1,3,3-tetrakis(trifluoromethanesulfonyl)propane represented by formula [4] and a compound represented by formula [5] to react with each other;
- wherein in the formula [1],
- R1 mutually independently represents a C1-C12 straight-chain, branched or cyclic alkyl or aromatic hydrocarbon group or a halogen atom, in which the alkyl or aromatic hydrocarbon groin may contain halogen wherein the halogen is selected from the group consisting of fluorine, chlorine, bromine and iodine an oxygen atom or a carbonyl bond instead of a part of hydrogen atoms;
- R2 mutually independently represent a hydrogen atom or a C1-C12 straight-chain,branched or cyclic alkyl group;
- “1” represents any integer from 0 to 2, “n” mutually independently represents any integer from 1 to 5, “m” mutually independently represents any integer from 0 to 4, “o” mutually independently represents any integer from 1 to 3, and m+n+o ≦6 is satisfied;
- wherein in the formula [5],
- R1 mutually independently represents a C1-C12 straight-chain, branched or cyclic alkyl or aromatic hydrocarbon group, in which the alkyl or aromatic hydrocarbon group may contain halogen, wherein the halogen is selected from the group consisting of fluorine, chlorine, bromine and iodine, an oxygen atom or a carbonyl bond instead of a part of hydrogen atoms;
- R2 mutually independently represent a hydrogen atom or a C1-C12 straight-chain, branched or cyclic alkyl group;
- “1” represents any integer from 0 to 2, “n” mutually independently represents any integer from 1 to 5, and “m” mutually independently represents any integer from 0 to (6-n);
- and
- wherein if there are two or more combinations of R1 and R2, each combination may be either an equal one or a different one.
