A series of phenanthridin-6-(5H)-ones were synthesized through a palladium-catalyzed C-H activation/cyclization strategy using diazonium salts in good yields. The best conditions included Pd(OAc)2 as the catalyst, PPh3 as the ligand, toluene as the solvent, K2CO3 as the base and 60 oC as the optimal temperature.
