Abstract
Ir(0) nanoparticles with 2.3 ± 0.4 nm in diameter prepared by simple reduction of [Ir(cod)Cl]2 in 1-n-butyl-3-methylimidazolium hexafluorophosphate ionic liquid constitute a simple, efficient and recyclable catalytic system for the solventless or biphasic hydrogenation of ketones under mild reaction conditions.
Key words
ionic liquids - hydrogenation - iridium - ketones - nanoparticles - biphasic catalysis
