A copper(I)-catalyzed intramolecular amination reaction using CuI, KOH, and 1,4-dioxane at 105°C for the preparation of 1-aryl-1H-indazole derivatives was described. The method was applied to a wide scope of substrates and afforded indazole products in hi

An efficient and divergent synthesis of N-arylbenzimidazoles and N-arylindazoles from arylamino oximes based on reaction conditions selection was developed. The synthesis was approached by treating oximes with BTC and the chemoselectivity was regulated by the amount of Et3N. This switchable N–N and N–C bond formation process features mild reaction conditions, simple execution, high chemoselectivity and broad substrate scope.
