实验过程

The reaction product obtained in step a) is admixed with 2.2 equivalents of I2 (based on the crude yield of acetyltriphenylene) in pyridine solvent at room temperature. Thereafter, the mixture is kept at reflux for 45 min, and then a further portion of I2 (1.0 equivalent) is added. After reflux for a further hour, NaOH, EtOH and water are added and the reaction mixture is heated to reflux for 2 h. 2-triphenylenecarboxylic acid is obtained in 76% yield (based on crude yield of acetyltriphenylene, or 74% based on triphenylene).
