Abstract

An object of the present invention is to provide a novel substance that has a high reactivity as a fluorinating agent, is effectively used in various fluorination reactions, and is safely handled even in air. As the solution for achieving this object, the present invention provides a complex obtained by reacting bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals in a nonpolar solvent. This complex serves as a fluorinating agent that provides excellent fluorination performance and that is stable in air.

First claim

1 . A complex (provided that BrF 3 .KF is excluded) consisting of bromine trifluoride and at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals.

2 . The complex according to claim 1 , wherein the complex exhibits an exothermic decomposition onset temperature in nitrogen of 40° C. or higher.

3 . The complex according to claim 1 , wherein the complex is a reaction product obtained by mixing bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals, in a nonpolar solvent.

4 . The complex according to claim 3 , wherein the reaction product is obtained by reacting 0.5 mol or more of the metal halide, per mol of bromine trifluoride.

5 . The complex according to claim 1 , wherein the metal halide is at least one member selected from the group consisting of a halogenated metal represented by the formula: MX, wherein M is M 1 or (M 2 ) 1/2 ), is an alkali metal, and M 2 is an alkaline earth metal, and X is a halogen atom; and a halogenated metal represented by the formula: MHX 2 , wherein M and X are as defined above.

6 . The complex according to claim 1 , wherein the metal halide is at least one potassium halide selected from the group consisting of halogenated potassium and halogenated hydrogen potassium.

7 . The complex according to claim 1 , wherein the metal halide is at least one potassium fluoride selected from the group consisting of fluorinated potassium and fluorinated hydrogen potassium.

8 . (canceled)

9 . A method for producing the complex of claim 1 , the method comprising:
mixing bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals, in a nonpolar solvent; and collecting the resulting solids content.

10 . A method for fluorinating a compound, the method comprising:
bringing the compound into contact with a complex consisting of bromine trifluoride and at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals.
