The invention discloses one kind belonging to organic synthesis field, more particularly, to a kind of preparation method of asymmetric azobenzene.By bicyclic 6 formic ether compounds of [3.1.0] hexane of 6 chlorine, 2 carbonyl and aryl hydrazine, in suitable organic solvent, ring-opening oxidation reaction occurs, obtains asymmetric azobenzene.The reaction needs to carry out at a certain temperature, and product can be isolated by the methods of recrystallization, column chromatography after reaction.This method has the characteristics that synthesis step is simple, easy to operate, of low cost, and the synthesis for asymmetric azobenzene provides new approach. |
