Selective hydrogenation of unprotected indole to indoline over N-doped carbon supported palladium catalyst

Mesoporous N-doped carbon supported palladium catalyst Pd@CN0.132 was able to efficiently catalyze unprotected indole to indoline under mild conditions. In the aqueous system, a selectivity of 100% and conversion of 96% was achieved under 313 K and atmospheric hydrogen gas.

Graphical abstractPalladium nanoparticles supported on mesoporous N-doped carbon, Pd@CN0.132, was found to be an effective catalyst for hydrogenation of unprotected indole to indoline. The reaction is highly chemoselective under mild conditions (313 K, atmospheric H2) in water as solvent.Figure optionsDownload full-size imageDownload as PowerPoint slide
