Using the copper-catalyzed azide-alkyne cycloaddition "click" reaction, a library of triazole amphiphiles with a variety of functional polar "heads" and hydrophobic or superhydrophobic "tails" was synthesized. The amphiphiles were evaluated for their ability to stabilize small Au nanoparticles, and, at the same time, serve as templates for nanocasting porous SiO2. One of the Au@SiO2 materials thus prepared was found to be a highly active catalyst for the Au nanoparticle-catalyzed regioselective hydroamination of alkynes.
利用铜催化的叠氮化物-炔烃环加成“点击”反应，合成了一系列具有各种功能性极性“头”和疏水或超疏水“尾”的三唑两亲物。评估了这些两亲物稳定小金纳米颗粒的能力，同时，它们还可作为制备多孔二氧化硅的纳米铸造模板。结果发现，由此制备的一种金@二氧化硅材料是金纳米颗粒催化炔烃区域选择性氢胺化反应的高效催化剂。
