In 2022,Sajjadi, Mohaddeseh; Nasrollahzadeh, Mahmoud; Ghafuri, Hossein; Baran, Talat; Orooji, Yasin; Baran, Nuray Yilmaz; Shokouhimehr, Mohammadreza published an article in International Journal of Biological Macromolecules. The title of the article was 《Modified chitosan-zeolite supported Pd nanoparticles: A reusable catalyst for the synthesis of 5-substituted-1H-tetrazoles from aryl halides》.HPLC of Formula: 15854-87-2 The author mentioned the following in the article:
A novel heterogeneous catalyst was developed using chitosan-zeolite supported Pd nanoparticles (PdNPs@CS-Zeo) and used in an efficient synthesis of 5-substituted-1H-tetrazoles I [Ar = Ph, 4-pyridyl, 4-MeC6H4, etc.] from aryl halides with high yields for relatively short reaction times with an easy work-up procedure. In this method, highly effective and reusable PdNPs@CS-Zeo catalyst was used in the reaction of various aryl iodides/bromides with K4[Fe(CN)6] as a non-toxic cyanide source to catalyze the [2 + 3] cycloaddition of the corresponding aryl nitriles with NaN3 in the sequential one-pot preparation of 5-substituted-1H-tetrazoles I. The synthesized PdNPs@CS-Zeo nanocatalyst was characterized using XRD, FTIR, TEM, HRTEM, XPS, Raman, TG-DTG, ICP-OES, BET, and EDS mapping. Addnl., the nanocatalyst could be effectively separated by filtration and reused for multiple times without significant decrease of catalytic activity. In the part of experimental materials, we found many familiar compounds, such as 4-Iodopyridine(cas: 15854-87-2HPLC of Formula: 15854-87-2)
4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. HPLC of Formula: 15854-87-2
