A molybdenum(VI)-catalyzed protocol for the synthesis of 2-aryl-2H-indazoles using pinacol as a reducing agent under neat reaction conditions has been demonstrated. The developed method gives an easy access to a wide range of 2-aryl-2H-indazoles in excellent yields. The present strategy excludes the use of P(III)-reagents as deoxygenating agents.
