Click reactions are not specific reactions, but they are a way of generating products that follow examples in nature by joining small moieties, with each other producing a huge molecule in a good yield. The mind of that reaction is used in biomolecules synthesis, pharmacological and various biometric applications. The first Click reaction is the Copper compounds-catalyzed reaction of an azide with an alkyne (CuAAC), this copper-catalyzed “click” does not require legands on the metal but the metal oxides also can accelerate the reactions. For enhancement the products of Click reactions we were replacing the copper compounds in a classical reaction by the prepared nanocopper compound (NPs). And measure the consumption of starting material. Behind the evolution is the catalytic effect of nanocopper compounding (NPs) on (H2O2). Owing to the huge surface area of nanocopper compound (NPs), it was found that: the (NPs) can speed up decomposition of H2O2, also can accelerate the classical click reaction.
