Eco-friendly and efficient catalyst-free synthesis of N-sulfonylimines from sulfonamides and aldehydes: crucial role of Al2O3 as a reusable dehydrating agent

Autor: Zaineb Litim, Hanen Slimi, Thierry Ollevier, Jamil Kraïem

Publikováno v: RSC Advances. 13:4431-4435

A green synthesis of N-sulfonylimines was developed involving the straightforward condensation of sulfonamides with aldehydes under green and catalyst-free conditions, mediated by neutral Al2O3 as an efficient and reusable dehydrating agent.
