Abstract
AbstractA simple and atom‐economical protocol for bis‐nitration of 1‐naphthylamides was firstly discovered with tert‐butyl nitrite (TBN) as nitro source and catalyzed by Cu(OAc)2. Assisted by picolinamide direction, the C2,4‐H bis‐nitration could be achieved with excess amount of TBN at 50°C in HOAc. A radical pathway and single electron transfer process might be involved in the bis‐nitration process.
