Thermoregulated phase-transfer iridium nanoparticle catalyst: highly selective hydrogenation of the CO bond for α,β-unsaturated aldehydes and the CC bond for α,β-unsaturated ketones

Abstract

In the same catalytic system, thermoregulated ligand Ph₂P(CH₂CH₂O)₂₂CH₃-stabilized iridium nanoparticles exhibited a totally different orientation for the hydrogenation of unsaturated carbonyl compounds, namely, highly selective hydrogenation of the CO bond for α,β-unsaturated aldehydes and the CC bond for α,β-unsaturated ketones.
