Application

1,2,4-Trimethylbenzene can be used as a reactant to synthesize:
  • 2,3,5-Trimethylbenzoquinone via oxidation reaction with phthaloyl peroxide under solvent-free conditions.      
  • 1,2,4,5-Tetramethylbenzene (durene) by methylation using syngas in the presence of Cu and Zn-based bifunctional catalysts.
  •  1,2,4-Oxadiazole derivatives via tandem reaction with nitroalkenes and nitriles in the presence of superacid CF3SO3H (TfOH).
