Abstract

Intermolecular and intramolecular Friedel–Crafts acylation reactions of various aliphatic and aromatic esters at room temperature with the use of very simple reagents and activating groups in are described. The products were obtained in good yield (60–85 %). The detailed mechanistic pathway was studied by DFT calculations and supported by experimental evidence.
