Palladium-Catalyzed Direct Ortho C–O bond construction of Azobenzenes with Iodobenzene diacetate via C–H Activation

Abstract A method of direct synthesis of ortho-acyloxylated azoarenes via palladium-catalyzed C–H bond activation was developed. The reaction proceeded was smoothly at room temprature and have better yield in shorter times. The obtained ortho-acyloxylated azoarenes could be efficiently converted into 2-hydroxyazobenzenes in good yields through a hydrolysis process.
