A process for preparing between neighbour para-substituted hydroxy, thio boric acid

A method of preparing phenylboronic acid ortho- meta- and para-substituted with hydroxy and mercapto is disclosed. The method includes adding a compound of a formula I into an organic solvent, adding 1.2-2.0 eq of acetyl chloride, lowering the temperature of the solution to a temperature between -10 DEG C and 0 DEG C, adding 0.1-0.3 eq of anhydrous aluminium chloride, heating to 20-120 DEG C, stirring for 2-10 h to obtain a compound of a formula II, adding an alkali to adjust pH to be 11-12 after TLC detection proves that the reaction is finished, layering, removing the organic layer, adding hydrochloric acid into the water layer to adjust pH to be 2-3, extracting with ethyl acetate, subjecting the organic layer to rotary drying, and beating the obtained crude product with a mixture of acetone or dichloromethane and n-heptane to obtain a solid product of a formula III, wherein R in the formula I is methyl or tert-butyl, and M in the formula I, M in the formula II and M in the formula III are oxygen simultaneously or sulfur simultaneously. The product produced by the method is high in purity and high in yield.
