PURPOSE: A method for preparing aromatic family boric acid is provided to be used as a core intermediate of electronic elements and medical products. CONSTITUTION: An aromatic family boric acid of chemical formula 3(Ar-B(OH)_2) is prepared by reacting an aryl magnesium halide of chemical formula 1(Ar-MgX) and alkyl boronate of chemical formula 2(B(OR)_3) under the presence of co-solvent at a certain temperature. Ar is a phenyl group, naphthyl group, fluorobenzyl group, or toluene group; and X is halogen group such as chlorine or bromine. The cosovlent is tetrahydrofurane(THF), methyl tetrahydrofurane, or ether as a basic solvent.
