General description

Flash vacuum pyrolysis of o-toluoyl chloride at 780°C and 0.5 mmHg yields benzocyclobutenone.

Application

  • Development of hydrophobic functionalized materials: o-Toluoyl chloride was utilized in the synthesis of novel hydrophobic functionalized UiO-66 materials. The study demonstrated the chemical′s role in enhancing the structural and physicochemical properties of these metal-organic frameworks, indicating potential applications in catalysis and adsorption processes (Narea et al., 2023).
