An electrochemical synthesis method for the selective N1-acylation of indazoles has been developed. This “anion pool” approach electrochemically reduces indazole molecules generating indazole anions and H2. Acidanhydrides are then introduced to the solution resulting in selective acylation of the N1-position of the indazoles. This procedure can also be applied to the acylation of benzimidazoles and indoles
