실험 절차

Moreover, that patent also discloses a method in which alminium sulfate 18 hydrate is used instead of water. Specifically, aluminium sulfate 18 hydrate is added to a toluene solution of tris (pentafluorophenyl) borane. After the solution is refluxed, insoluble alminium sulfate is separated from the reaction mixture. A solvent of a filtrate is removed in vacuo. Toluene is added to the thus obtained residue. After stirring, the insoluble matter passes through a G4 sintered-glass so as to be separated. The solvent of the filtrate is again removed in vacuo. Heptane is added to the residue. The solution is stirred and filtered so that a cake is obtained. Finally, the thus obtained cake is washed with heptane, and dried in vacuo so as to isolate bis (pentafluorophenyl) borinic acid. However, this method has such a problem that it is necessary to remove the by-product alminium sulfate and its process is so complicated.
