摘要:
The first invention relates to a process for preparing fluorinated arylmagnesium derivatives by reacting a fluorinated aromatic compound with a halogenated hydrocarbon and magnesium in an ethereal solvent or a mixture thereof with a hydrocarbon. According to this process, the objective compound can efficiently be prepared in one reaction step at a low cost. The obtained arylmagnesium derivatives are useful as reagents for introducing fluorinated aromatic groups into various organic compounds. The second invention relates to a process for preparing (fluorinated aryl) boron compounds by adding an ethereal solution of a fluorinated arylmagnesium derivative and an ethereal solution of a boron halide to a hydrocarbon having a boiling point higher than that of the solvent and reacting the arylmagnesium derivative with the boron halide while distilling away the solvent. This process makes it possible to prepare objective boron compounds selectively and at a low cost, thus being industrially advantageous. The obtained boron compounds are useful as co-catalysts for metallocence catalysts.

摘要:
A method for stabilizing an aryl boron compound of formula (1): wherein Ar1, Ar2, and Ar3 are aryl groups, including mixing a compound which has higher affinity for the aryl boron compound than water, as a stabilizer, in a solution or slurry containing the aryl boron compound in a hydrocarbon solvent; and a stabilized composition obtained thereby. The stabilizing method and the stabilized composition of the present invention make it possible to store aryl boron compounds stably over a long term, while keeping their high purity, in the form of forming a substantially homogeneous system in the case of a solution or in the form of forming a substantially homogeneous system by heating in the case of slurry.
