Ultrasound-promoted green approach for the synthesis of sulfonamides using natural, stable and reusable Natrolite nanozeolite catalyst at room temperature

- Synthesis of sulfonamides under mild conditions and ultrasound irradiation.
- Reaction catalyzed by natural and reusable heterogeneous catalyst.
- Catalyst can be easily recovered and reused.
- Better reaction times, higher yields and easier work-up.
- Side product was not observed under the reaction conditions.
