CoPd alloy nanoparticles catalyzed tandem ammonia borane dehydrogenation and reduction of aromatic nitro, nitrile and carbonyl compounds

Composition-controlled catalysis of reduced graphene oxide supported CuPd alloy nanoparticles in the hydrolytic dehydrogenation of ammonia borane

“…The higher dispersion of RGO in aqueous solution makes the CuPd alloy NPs and AB interaction more facile. In our recent studies, we also reported that RGO was also good support material for NiPd and CoPd alloy NPs in the organic reactions owing to theinteraction between the aromatic substrates and the RGO [40,41]. Secondly, the RGO-Cu 75 Pd 25 catalysts were annealed at 400 • C for 1 h under Ar-H 2 flow (5% H 2 ) and its activity was compared to pristine RGO-Cu 75 Pd 25 (Fig.…”

Three‐Component Cascade Reaction in a Tube: In Situ Synthesis of Pd Nanoparticles Supported on mpg‐C3N4, Dehydrogenation of Ammonia Borane and Hydrogenation of Nitroarenes

“…However, a suitable catalyst is needed to facilitate both reactions concomitantly. In this regard, we have reported that palladium (Pd) based nanocatalysts were highly efficient for facilitating the tandem dehydrogenation of AB and selective hydrogenation of a variety of nitroarenes . In these studies, the nanoparticles (NPs) were prepared by the ex situ route including surfactant‐assisted chemical reduction of metal precursors in hot organic solution and then supported them on a high‐surface area carbon‐based materials.…”

Synthesis of Fluoranthene Derivatives via Tandem Suzuki–Miyaura and Intramolecular C–H Arylation Reactions under Both Homogeneous and Heterogeneous Catalytic Conditions

“…As the classical heterogeneous catalysts have limited surface area resulting in low activity, nanocatalysts emerged as highly efficient catalysts for various organic reactions in recent years owing to their high surface-to-volume ratio. 11 In this respect, Metin research group has demonstrated that bimetallic Pd nanoparticles (NPs) assembled on reduced graphene oxide (rGO) were highly efficient catalysts in a variety of organic transformations; 12 especially, rGO-assembled CuPd alloy NPs (rGO-CuPd) were shown to be highly efficient heterogeneous catalysts in Sonogashira cross-coupling reactions. 12a By the motivation of these promising results, we selected the rGO-CuPd nanocatalyst as a heterogeneous catalyst to be tested in this transformation.…”
