coupling reaction of nitroarenes with phenols has been developed. A series of N-cyclohexylaniline derivatives was easily and efficiently obtained in moderate to good yields via C–N bond formation by the simple use of safe and inexpensive sodiumformate as the hydrogen donor. A direct and efficient palladium-catalyzed reductive coupling reaction of nitroarenes with phenols has been developed. A series of

and 14 ketones. In our ongoing efforts in preparing tool compounds for investigating and controlling the biosynthesis of phenazines, we recognized the limitations of existing protocols for C–N bond formation of electron-deficient anilines when usingreductiveamination. After extensive optimization, we have established three robust and scalable protocols for the reductiveamination of ketones with electron-deficient
