第一个Au催化的烯烃硅氢加成反应的例子是使用可回收的金纳米颗粒作为催化剂，而不需要任何外部配体或添加剂。氢硅烷加成反应以高度区域选择性的方式发生在末端联烯的双键上。观察到的区域选择性/反应性模式归因于空间和电子因素。
The first example of Au-catalyzed hydrosilylation of allenes is presented using recyclable gold nanoparticles as catalyst, without the requirement of any external ligands or additives. The hydrosilane addition takes place on the more substituted double bond of terminal allenes in a highly regioselective manner. The observed regioselectivity/reactivity modes are attributed to steric and electronic factors.
