Thermoregulated phase-transfer iridium nanoparticle catalyst: highly selective hydrogenation of the C = O bond for alpha,beta-unsaturated aldehydes and the C = C bond for alpha,beta-unsaturated ketones

摘要

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