Since, Lewis acids could increase the yield of 1,3-dipolar reactions in the shorter reaction time, we examined Fe 3 O 4 @SiO 2 @Au NPs as Lewis acid in the model reaction (entry 11). To our delight, the reaction in the presence of Fe 3 O 4 @SiO 2 @Au ( mol%) using NaHCO 3 as base in THF at 45 °C gave the product in 85% yield.
