Abstract: A new eco-friendly approach for the preparation of sustainable heterogeneous palladium catalysts from rice husk-derived biogenic silica (RHP-Si and RHU-Si). The designed heterogeneously supported palladium species (RHP-Si-NH2-Pd and RHU-Si-NH2-Pd) were fully characterized and successfully employed as catalysts for various chem. transformations (C-C bond-forming reactions, aerobic oxidations and carbocyclizations). Suzuki-Miyaura transformations were highly efficient in a green solvent system (H2O:EtOH (1:1) with excellent recyclability, providing the cross-coupling products with a wide range of functionalities in high isolated yields (up to 99%). Palladium species (Pd(0)-nanoparticles or Pd(II)) were also efficient catalysts in the green aerobic oxidation of an allylic alc. and a co-catalytic stereoselective cascade carbocyclization transformation. In the latter case, a quaternary stereocenter was formed with excellent stereoselectivity (up to 27:1 dr). In the experiment, the researchers used many compounds, for example, 4-Iodopyridine(cas: 15854-87-2Product Details of 15854-87-2)
4-Iodopyridine(cas: 15854-87-2) is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists. 4-Iodopyridine is a halogenated heterocycle that is a building block for proteomics research.Product Details of 15854-87-2
