A method for catalytic oxidation of aromatic boron compound prepared phenol

The present invention discloses a method of catalytic oxidation of aromatic boron compounds synthesized phenolic compounds, in an aqueous solvent such as alcohol or alcohol, under the action of a base, was added hydrazine hydrate or hydrazine compound catalyst, the catalytic oxidation of aromatic boron compound directly preparation of phenolic compounds. The method of preparation of phenolic compounds of the present invention, the catalyst is inexpensive hydrazine hydrate or compound, the oxidizing agent is air or oxygen at atmospheric pressure, and good reaction activity without the metal catalyst, a wide and stable sources of substrates, substrates sensitive functional groups good compatibility and a wide range. Under the optimized reaction conditions, the target product isolated yield of 99%.
