Triphenylene synthesis

10synthesis methods
Triphenylene synthesis: 2-Chlorobenzoic acid(78mg, 0.5mmol), iodonium salt (236mg, 0.55mmol), palladium acetate (2.8mg, 0.0125mmol), potassium carbonate (152mg, 1.1mmol) were dissolved in 3mL of NMP solvent was heated to 110 °C and stirred for 17 hours, cooled to room temperature, extracted with ethyl acetate, washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, concentrated, and subjected to column chromatography to obtain 92 mg of triphenylene as a white solid, The yield was 80%.
