So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhou, Enmu; Jin, Jianzhong; Zheng, Kai; Zhang, Letian; Xu, Hao; Shen, Chao researched the compound: 2-Phenylpyridine( cas:1008-89-5 ).Recommanded Product: 1008-89-5.They published the article 《Novel Recyclable Pd/H-MOR Catalyst for Suzuki-Miyaura Coupling and Application in the Synthesis of Crizotinib》 about this compound( cas:1008-89-5 ) in Catalysts. Keywords: zeolite support palladium nanocatalyst preparation surface area green chem; haloarene phenyl boronic acid palladium nanocatalyst Suzuki Miyaura coupling; phenyl arene preparation. We’ll tell you more about this compound (cas:1008-89-5).
In this paper, an effective ultrasound method for the synthesis of Pd/H-MOR, which was used as a catalyst in the Suzuki-Miyaura coupling of aryl halides with phenylboronic acids was reported. The structure and morphol. of the as-prepared catalysts were fully characterized by X-ray diffraction (XRD), N2 sorption isotherms, SEM (SEM) and an inductively coupled plasma-at. emission spectrometer (ICP-AES). The advantages of Pd/H-MOR in the coupling reaction are green solvents, high yields, absence of ligands and recyclability. The catalysts were easily reused at least ten times without significant deterioration in catalytic activity. In addition, this protocol was used in the marketed anti-tumor drug crizotinib synthesis.
As far as I know, this compound(1008-89-5)Recommanded Product: 1008-89-5 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
