Copper oxide-Titanium dioxide nanocomposites (CuO/TiO2 NC) is an efficient photocatalyst for the synthesis of 2H-indazoles derivatives through intermolecular C-N bond (Ullmann Goldberg reaction) and intramolecular N-N bond formation. The CuO/TiO2 NC is a stable photocatalyst and can be reused multiple times without losing its catalytic properties. High yields of product, environmentally friendly, cost-effective method, and easy workup are advantages of the present method. All synthesized compounds were characterized by NMR spectroscopy.
