in 1 h was achieved with 1:3 molar ratio of hydrazone to calcium hypoch lorite. The use of alumina- supported calcium hypochlorite as a heterogeneous oxidant in this reaction has advantage of enhanced reaction rate and yield, simple work-up, low cost, and eco-friendly reagent when compared to other oxidants such as bromine,
