Application
Insertion of Benzene Rings into the Amide Bond

Typical Procedure: To a solution of the amide (0.250 mmol) and TBAT (0.500 mmol) in toluene (3 mL) is added the benzyne precursor (0.375 mmol). The reaction is heated at 50℃ for 16 h and concentrated under reduced pressure. The resulting mixture is purified by flash chromatography on silica gel (dry loading) to afford the desired product.
