Ultrasound Accelerated Expedient and Eco-Friendly Synthesis of Aryl Sulfonates Using I2 As Catalyst At Ambient Conditions

Aryl sulfonates were developed by ssing an energy-saving and eco-friendly approach, through ultrasound-assisted coupling reaction of readily sodium sulfinates with N-hydroxyphthalimide, under metal-free and mild conditions within 10 min at room temperature.
