Nano palladium supported on high‐surface‐area metal–organic framework MIL‐101: an efficient catalyst for Sonogashira coupling of aryl and heteroaryl bromides with alkynes

Abstract

Palladium nanoparticle-incorporated metal-organic framework MIL-101 (Pd/MIL-101) was successfully synthesized and characterized using X-ray diffraction, nitrogen physisorption, X-ray photoelectron, UV-visible and infrared spectroscopies, and transmission electron microscopy. The characterization techniques confirmed high porosity and high surface area of MIL-101 and high stability of nano-size palladium particles. Pd/MIL-101 nanocomposite was investigated for the Sonogashira cross-coupling reaction of aryl and heteroaryl bromides with various alkynes under copper-free conditions. The reusability of the catalyst was tested for up to four cycles without any significant loss in catalytic activity.

Self‐Generation of Surface Roughness by Low‐Surface‐Energy Alkyl Chains for Highly Stable Superhydrophobic/Superoleophilic MOFs with Multiple Functionalities

“…More evidence is provided by control experiments utilizing various organic solvents, in which only low conversion was observed (see Table S9). In contrast to previously reported heterogeneous catalysts for the Sonogashira reaction (see Table S10), superhydrophobic UiO‐67‐Oct‐L 2 ‐35.7 %‐Pd II is also able to effectively catalyze the reaction at ambient temperature without heating, thus acting as an environmentally friendly and cost‐saving heterogeneous catalyst.…”

Facile fabrication of g‐C3N4/MIL‐53(Al) composite with enhanced photocatalytic activities under visible‐light irradiation

“…Metal–organic frameworks (MOFs) are an interesting class of porous crystalline structures formed by the linking of bridging ligands and metal‐connecting nodes . Some MOFs, such as MOF‐5, ZIF‐8, ZIF‐67, UIO‐66, UIO‐67 and MIL‐100(Fe), that act as photocatalysts in the decomposition of organic dye molecules have been investigated.…”
