Yield:-

Reaction Conditions:

with palladium-decorated gold nanoparticles anchored on amphoteric zirconia in n-heptane at 300; under 30402 Torr; for 6 h;

Steps:

General Procedure for Dehydrative Aromatization of DMF into PX
General procedure: A mixture of DMF (1mmol), catalysts (designated amount), n-heptane (5mL), andnaphthalene (1mmol, as the internal standard) were charged into a 50-mL Hastelloy-C high-pressure Parr reactor. The resulting mixture was vigorously stirred (800rpm) under an ethylene atmosphere (40 atm) at the designated temperature for the given reaction time. After completion of the reaction, the reaction mixture was filtered and the catalyst was washed thoroughly with ethanol. The filtrate was then collected and analyzed by an Agilent 7820A gas chromatograph equipped with an HP-INNOWax column (30m × 0.32mm × 0.25μm) and an FID. All of the products were identified by GC-MS, and the spectra obtained were compared with the standard spectra.
