Palladium nanoparticlecatalysts in ionic liquids: synthesis, characterisation and selective partial hydrogenation of alkynes to Z-alkenes†
Abstract
The simple heating (120 °C) of Pd(OAc)2 in 1-butyronitrile-3-methylimidazolium-N-bis(trifluoromethane sulfonyl)imide ((BCN)MI·NTf2) under reduced pressure leads to the formation of stable and small-sized Pd(0)-NPs (diameter: 7.3 ± 2.2 nm). These metal
