Special Topic Amination Reactions in Organic Synthesis Abstract 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

Pd-catalyzed selective amine-oriented C8-H bond functionalization/N-dealkylative carbonylation of naphthyl amines has been achieved. The aminegroup from dealkylation is proposed to be the directing goup to promote this process. It...
