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.

Interestingly, in contrast Ganguly’s report [10] and in a same reaction condition when chiral. In this way, name reactions have become part of the shared vocabulary of organic synthesis chemists. When meeting a fellow chemist, for example at a conference or during a job interview, it is possible to make an initial assessment of your listener’s level and depth of expertise and experience by referring to an exotic name reaction.

The 1,3-dipolar cycloaddition reaction that weds an azide with an alkyne has emerged as a powerful ligation strategy with applications in biology, 1 medicine, 2,3 and material science. 4 The pioneering work of Huisgen 5 and the revitalizing efforts of Sharpless 6,66 and Meldal 7 have provided a foundation for the recent explosion of copper-free strain-promoted.
