HAPpy catalysts: Hydroxyapatite‐supported gold nanoparticles efficiently catalyze the deoxygenation of amides, sulfoxides, and pyridine N‐oxides, with silanes as reductants, to give the corresponding products with excellent turnover numbers (see graphic). Furthermore, this catalyst is easily recovered and reused without any loss of efficiency.
HAPpy催化剂:以羟基磷灰石为载体的金纳米颗粒,以硅烷为还原剂,可有效催化酰胺,亚砜和吡啶N-氧化物的脱氧反应,从而制得具有优异周转率的相应产品(见图)。此外,该催化剂易于回收和再利用而没有任何效率损失。
