Method for producing tetrakis ( fluoroaryl) borate-magnesium compound

Fluoroaryl magnesium halide is reacted with a boron compound so that a molar ratio of the fluoroaryl magnesium halide to the boron compound is not less than 3.0 and not more than 3.7, so as to produce a tetrakis (fluoroaryl) borate·magnesium compound. With this method, there occurs no hydrogen fluoride which corrodes a producing apparatus and requires troublesome waste water treatment.

Synthesis and mesomorphic properties of some liquid crystals with 2,3,5,6-tetrafluorophenylene unit

Nine fluorosubstituted liquid crystals have been synthesized and their mesomorphic properties have been studied by texture observation in a polarizing microscope and confirmed by DSC. They show enantiotropic smectic A and nematic phases. The effect of ter
