Moreover, the substrate scope for aromatic partner 2 was also explored. Cyanoaromatics 35-38 successfully underwent coupling with 1 to furnish arylated products in moderate to good yields (35a-38a). In contrast, , the product involving two-electron transfer was predominantly obtained in most cases in moderate to low yields (1b) under DC electrolysis. The arylated product 38a was a 1:0.6 mixture of two isomers due to lack of regioselectivity in elimination of CN -group in reaction. The coupling of 1 with electron-deficient heteroaromatics such as 4-cyanopyridine (43), 2chlorobenzthiozole (44) and 2-chlorobenzoxazole (45) were not successful using AC or DC electrolysis (Figure ).
