Polymeric graphitic carbon nitride (g‐C 3 N 4 ) supported CuBr 2 hybrid material (CuBr 2 @g‐C 3 N 4 ) was developed by impregnation of CuBr 2 on g‐C 3 N 4 sheets. The morphology and physiochemical properties were analyzed by powder XRD, SEM, and HRTEM studies. The hybrid CuBr 2 @g‐C 3 N 4 material showed excellent selectivity in the aerobic oxidation of primary/secondary alcohols and benzoins to the corresponding carbonyl compounds in absence of any oxidizing agents. Further, CuBr 2 @g‐C 3 N 4 demonstrated direct oxidation of toluene derivatives to corresponding aldehydes in excellent yields. The g‐C 3 N 4 support provides excellent stability and heterogeneity to CuBr 2 and was recovered simply by filtration and reused for ten times without appreciable loss in catalytic activity.
