Method for the preparation of diphenyl ether compounds
-
Paragraph 0038-0040, (2016/12/01)
The invention relates to a method for preparing a diphenyl ether compound. The method is characterized by comprising the following technical steps of: (1) adding a halogenated benzene derivative and a bis(pinacolato)diboron into a reaction vessel, adding copper chloride or aluminum chloride and 1,2-bi(diphenylphosphine) ethane as a catalyst, then adding alkaline and an organic solvent, and reacting at 25-160 DEG C for 6-24 hours; and (2) after extracting a reaction solution obtained from the step (1) by using ethyl acetate, purifying by a 200-300 meshes silica gel column, pre-eluting the silica gel column by using 20-50 mL of normal hexane, eluting by adopting an eluent at a flow speed of 1-2 mL/min for 3-6 hours, and removing the solvent to obtain the diphenyl ether compound. The method for preparing the diphenyl ether compound, disclosed by the invention, no only overcomes the disadvantage of the use of phenolic substances in a reaction process, but also has the advantages of mild reaction condition and high yield.
