Iridium complex immobilized on a high-nitrogen containing covalent triazine framework derived from 2,5-pyrazinedicarbonitrile as a recyclable catalyst for the selective N-alkylation of aminobenzenesulfonamides with alcohols

Abstract

A new-type of covalent triazine framework derived from 2,5-pyrazinedicarbonitrile as a monomer with a high N/C ratio was designed and synthesized by trimerization at 400 °C with ZnCl2 as a catalyst and salt melt via the ionothermal technique.
