One-pot synthesis of aniline derivatives from nitroarenes under mild conditions promoted by a recyclable polymer-supported palladium catalyst

Esterification, transesterification and hydrogenation reactions of polyunsaturated compounds catalyzed by a recyclable polymer supported palladium catalyst

“…Pd-pol was synthesized according to the procedure described in ref. [30]. Commercial edible oil was composed by all cis -5,8,11,14,17- was let to reach room temperature, the hydrogen was vented and the autoclave opened.…”

“…In all cases, the pristine Pd(II) supported complex was reduced in situ under reaction conditions to Pd(0), forming palladium nanoparticles (NPs) (the real active species) immobilized onto the insoluble support (Pd-pol, Scheme 1) and stabilized by the macroporous and reticulated polymer matrix [36]. These NPs showed a size distribution centered around 4 nm (when formed under 1 atm H 2 in methanol as the solvent), retaining their morphology and roughly their dimension even after several catalytic runs in hydrogenation reactions [30].…”

“…A C C E P T E D Pd-pol pre-catalyst was successfully employed in several palladium promoted reactions [26,27,28,29,30,31,32,33,34,35]. In all cases, the pristine Pd(II) supported complex was reduced in situ under reaction conditions to Pd(0), forming palladium nanoparticles (NPs) (the real active species) immobilized onto the insoluble support (Pd-pol, Scheme 1) and stabilized by the macroporous and reticulated polymer matrix [36].…”

Programmed Synthesis Palladium Supported on Fe3O4@C: An Efficient and Heterogeneous Recyclable Catalyst for One-Pot Reductive Amination of Aldehydes with Nitroarenes in Aqueous Reaction Medium

“…In recent years, many attempts have been made to disperse palladium nanoparticles on support materials which showed high catalytic activities toward the reductive amination reaction [16,17]. One-pot transformations are economically, ecologically and highly intriguing for developing efficient new synthetic processes.…”

Selective catalytic amination of halogenated aldehydes with calcined palladium catalysts

“…[20][21][22] The drawback of using Pd catalysts in the case of amination of halogen substituted carbonyl compound is its capability to displace the halogen atom by a hydrogen atom. A strategy to avoid the undesired dehalogenation is to modify the Pd active sites.…”
