An　electrochemical　CH　acylation　of　electron-deficient　Nheteroarenes　with　a-keto　acids　is　reported,　This　first　electrochemical　Minisci　acylation　reaction　proceeded　using　NH4I　as　a　redox　catalyst.　A　broad　N-heteroarene　scope　and　high　functional　group　tolerance　are　observed.　Selective　monoacylation　of　N-heteroarenes　is　achieved　via　control　of　acyl　radical　at　a　low　concentration.　The　results　of　cyclic　voltametry　and　control　experiments　disclose　that　the　electrogenerated　I-2　is　likely　the　active　species　to　initiate　the　oxidative　decarboxylation　of　carboxylate　anion　via　an　acyl　hypoiodite　intermediate.　The　electrochemical　Minisci　acylation　provides　a　straightforward　approach　for　the　late-stage　functionalization　of　pharmacophores.
