The porous crosslinked polymer–iridium composite TTEB@Ir catalyzed the selective synthesis of acylhydrazone and benzenesulfonylhydrazone derivatives†

The search for highly active and efficient ligands is crucial in coordination polymer-based catalysis applications. Porous crosslinked polymer–iridium composites TTEB@Ir containing triazole framework ligands were synthesized and fully characterised by various modern means. The resulting composites were found to exhibit high catalytic activity for the selective synthesis of N-acylhydrazone and benzenesulfonylhydrazone derivatives. In addition, the porous crosslinked polymer-based composites showed impressive recyclability, proving their economic and environmental merits, while mechanistic studies shed light on these transformations.
