Herein, we report Ru(II)-catalyzed C–H/N–H bond functionalization of N-chlorobenzamides with 1,3-diynes via regioselective (4 + 2) annulation for the synthesis of isoquinolones under redox-neutral conditions at roomtemperature. This represents the first example of C–H functionalization of N-chlorobenzamides using an inexpensive and commercially available [Ru(p-cymene)Cl2]2 catalyst. The reaction is
