Catalytic hydrosilylation represents a straightforward and atom-efficient methodology for the creation of C–Si bonds. In general, the application of homogeneous platinum complexes prevails in industry and academia. Herein, we describe the first heterogeneous single atom catalysts (SACs), which are conveniently prepared by decorating alumina nanorods with platinum atoms. The resulting stable material efficiently catalyzes hydrosilylation of industrially relevant olefins with high TON (≈10⁵). A variety of substrates is selectively hydrosilylated including compounds with sensitive reducible and other functional groups (N, B, F, Cl). The single atom based catalyst shows significantly higher activity compared to related Pt nanoparticles.

单原子基多相铂催化剂的合成：高选择性和氢化硅烷化反应的活性。

催化氢化硅烷化是创建C-Si键的一种简单且原子高效的方法。通常，在工业界和学术界普遍使用均相铂络合物。在这里，我们描述了第一种非均相单原子催化剂（SAC），可以通过用铂原子修饰氧化铝纳米棒来方便地制备它们。将得到的稳定的材料有效地催化具有高TON（≈10工业相关的烯烃的氢化硅烷化⁵）。多种底物被选择性地氢化硅烷化，包括具有敏感的可还原基团和其他官能团（N，B，F，Cl）的化合物。与相关的Pt纳米颗粒相比，单原子基催化剂显示出明显更高的活性。
