Palladium Nanoparticles Encapsulated in a Metal–Organic Framework as Efficient Heterogeneous Catalysts for Direct C2 Arylation of Indoles
Abstract
Highly dispersed palladium nanoparticles (Pd NPs) encapsulated in the mesoporous cages of the metal–organic framework (MOF) MIL‐101(Cr) have been prepared by using the wetness impregnation method. The Pd NPs were characterized by powder X‐ray diffraction (PXRD), N 2 adsorption, transmission electron microscopy, inductively coupled plasma atomic emission spectroscopy (ICP‐AES), and X‐ray photoelectron spectroscopy (XPS). The particles size ((2.6±0.5) nm) of the obtained Pd NPs was in good agreement with the cage diameters (2.9 and 3.4 nm) of the MOF. The resulting Pd/MIL‐101(Cr) catalyst exhibited extremely high catalytic activities in the direct C2 arylation of substituted indoles by using only 0.1 mol % of the Pd catalyst. Moreover, the catalyst is easily recoverable and can be reused several times without leaching into solution and loss of activity. The combination of the highly dispersible Pd NPs within the accessible mesoporous cages and the favorable adsorption of the aryl halides on MIL‐101 are suspected to be the main reasons for the observed high activities of the Pd/MIL‐101(Cr) catalyst in the direct C2 arylation of indoles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
