hypervalent iodine(III)-mediated in-cell synthesis of 3,4-dihydroquinolin-2-ones by C−N coupling is established, applying catalytic amounts of reagents, inexpensive electrode materials and a simple galvanostatic set-up. With this method 23 examples in yields up to 96 % could be synthesized, exhibiting various functional groups. Furthermore, a 10-fold scale-up was performed and a reaction mechanism was proposed
