Silver-Catalyzed para -Selective C-H Amination of 1-Naphthylamides with Azodicarboxylates at Room Temperature

A simple and efficient protocol for para -selective C-H amination of 1-naphthylamide derivatives under silver catalysis is described. This reaction system could proceed without the help of directing group and a broad range of substrates were proved to be well tolerated. In addition, control experiments suggested that this reaction might not proceed via a single-electron-transfer process.
