This study details the isolation and characterisation of three novel silver(I) amides in solution and solid-state, [Ag(Cy P)(HMDS)] 2, [Ag(Cy P){N(TMS)(Dipp)}] 3 and [Ag(Cy P) (NPh )] 4. Their catalytic abilities have proved successful in hydroboration and hydrosilylation reactions with a full investigation performed with complex 2. Both protocols proceed under mild conditions, displaying exceptional functional-group tolerance and chemoselectivity, in excellent conversions at competitive reaction times. This work reveals the first catalytic hydroboration of aldehydes and ketones performed by a silver(I) catalyst.
本研究详细阐述了三种新型银（I）酰胺在溶液和固态中的分离与表征，即[Ag(Cy P)(HMDS)]₂、[Ag(Cy P){N(TMS)(Dipp)}]₃和[Ag(Cy P)(NPh)]₄。已证明它们在硼氢化和硅氢化反应中具有催化能力，并对配合物2进行了全面研究。两种反应方案均在温和条件下进行，表现出出色的官能团耐受性和化学选择性，在具有竞争力的反应时间内转化率极高。这项工作揭示了首例由银（I）催化剂进行的醛和酮的催化硼氢化反应。
