Visible Light-Assisted Direct C-H Acyloxylation of Polycyclic Aromatic Hydrocarbons using Carboxylic Acids

The direct C-H acyloxylation of polycyclic aromatic hydrocarbons (PAHs) with carboxylic acids as the acyloxylating agents was achieved via the electron-donor-acceptor (EDA) complexes between PAHs and N-iodosuccinimide (NIS). This visible light-assisted metal-free C-H acyloxylation reaction provides an easy access to the desired aryl carboxylates from readily available PAHs and aliphatic and aromatic carboxylic acids under mild reaction conditions.
