摘要

Solid-supported nano and microparticles of Pd(0) (SS-Pd) were prepared and used as heterogeneous catalysts for Suzuki-Miyaura cross coupling reactions of aryl halides (chloro, bromo and iodo) and phenyl boronic acid under mild and ligand-free conditions. Scanning electron microscope (SEM) and UV-vis based studies were performed to observe the distribution of nano and microparticles of palladium over solid surface and their oxidation states. In addition, the catalyst could be reused up to seven runs without significant loss of activity and stable enough under moist conditions. (C) 2011 Elsevier Ltd. All rights reserved.

Sustainable nano fibrillated cellulose supported in situ biogenic Pd nanoparticles as heterogeneous catalyst for C-C cross coupling reactions

Anindita Dewan, Manashi Sarmah, Prantika Bhattacharjee, Pankaj Bharali, Ashim J. Thakur, Utpal Bora

Summary: This study reports the design, synthesis, and application of naturally occurring cellulose from agro waste pomegranate peel as a novel support for active biogenic Pd nanoparticles for Suzuki-Miyaura and Sonogashira cross-coupling reactions at room temperature. The cellulose matrix enables well dispersion of Pd nanoparticles over the support to generate Pd@cellulose, exhibiting excellent catalytic activity and recyclability under ligand-free mild reaction conditions. The synthesized cellulose nanofibers and Pd-anchored heterogeneous nanofibers were characterized through various analytical techniques.

Hollow-Shell-Structured Mesoporous Silica-Supported Palladium Catalyst for an Efficient Suzuki-Miyaura Cross-Coupling Reaction

Abdulelah Taher Ali Mohammed, Lijian Wang, Ronghua Jin, Guohua Liu, Chunxia Tan

Summary: The high stability heterogeneous catalyst HS@PdPPh2@MSN was constructed by immobilizing bis((diphenylphosphino)ethyltriethoxysilane)palladium acetate onto the inner wall of a mesoporous organicsilicane hollow shell, showing a well-defined single-site active species within the silicate network. It enabled an efficient Suzuki-Miyaura cross-coupling reaction with up to 95% yield in mild conditions, and could be reused at least five times with good activity, making it a cost-effective and easily synthesized candidate for fine chemical engineering.

Palladium Supported on Bioinspired Materials as Catalysts for C-C Coupling Reactions

Gianluigi Albano, Antonella Petri, Laura Antonella Aronica

Summary: In recent years, there has been extensive research on immobilizing palladium nanoparticles on solid supports for the preparation of active and stable catalytic systems. Compared to inorganic materials, naturally occurring organic solids are more cost-effective and readily available. This review focuses on the application of metal catalysts supported by natural biomaterials in C-C bond formation reactions, specifically Mizoroki-Heck, Suzuki-Miyaura, and Sonogashira reactions. Different types of organic matrices, such as cellulose, starch, pectin, agarose, chitosan, as well as proteins and enzymes, are discussed, highlighting the heterogeneous nature and recyclability of each catalyst.

Silk-Fibroin-Supported Palladium Catalyst for Suzuki-Miyaura and Ullmann Coupling Reactions of Aryl Chlorides

Giorgio Rizzo, Gianluigi Albano, Teresa Sibillano, Cinzia Giannini, Roberta Musio, Fiorenzo G. Omenetto, Gianluca M. Farinola

Summary: This paper reports the application of a silk fibroin-supported Palladium catalyst (Pd/SF) in Suzuki-Miyaura and Ullmann coupling reactions of aryl chlorides. The existence of catalytic pockets where monoatomic palladium species can form stable complexes with SF is hypothesized and supported by experimental analysis. The size of the catalytic pocket of Pd/SF is estimated to be approximately 15 angstroms using computational modeling.

Zeolite-encaged palladium catalysts for heterogeneous Suzuki-Miyaura cross-coupling reactions

Mingyang Gao, Jiamin Wang, Weixiang Shang, Yuchao Chai, Weili Dai, Guangjun Wu, Naijia Guan, Landong Li

Summary: Suzuki-Miyaura cross-coupling reaction is a powerful method to construct carbon-carbon bonds and is widely used in the synthesis of functional organic compounds. In this study, zeolite-encased Pd particles (Pd@MFI) were successfully prepared and investigated as promising heterogeneous catalysts for the Suzuki-Miyaura cross-coupling reaction. The Pd@MFI catalysts showed high activity, with dispersed Pd particles efficiently stabilized within the MFI zeolite matrix. The presence of basic sites adjacent to Pd sites was crucial for achieving high catalytic activity.

Tungsten-doping promoted catalytic activity of polyaniline-supported palladium for the Suzuki-Miyaura coupling reaction

Yiyang Zhang, Hong Sun, Yonghuai Yang, Haofei Li, Yaocheng Shi, Lei Yu

Summary: The catalytic activities of palladium nanoparticles on a polyaniline support were improved by tungsten doping, resulting in a significantly increased catalyst turnover number (>10(4)) for the Suzuki-Miyaura coupling reaction. Characterization of the materials showed that tungsten doping improved the micro-morphology, leading to more efficient absorption of reactants. Additionally, tungsten facilitated stabilization of Pd(0) species and the transmetallation step, both crucial for the catalytic reaction. Therefore, Pd/W@PANI engineering material may serve as a highly efficient heterogeneous catalyst in the pharmaceutical industry.
