摘要:
A nickel-catalyzed electrochemical methodology for the Minisci acylation of aromatic electron-deficient heterocycles with alpha-keto acids has been developed. The reaction is performed in an undivided cell under constant current conditions, featuring broad scope of substrates and avoiding the conventional utilization of silver-based catalysts in conjunction with excess amount of oxidants. Cyclic voltammetric analysis disclosed that a ligand-to-metal electron transfer process may be involved in the generation of the key acyl radicals. (C) 2019 Elsevier Inc. All rights reserved.
