Solvent-Free Synthesis of Aryl Iodides Using Nano SiO2/HIO4 as a Reusable Acid Catalyst

در اين مقاله روش مناسب و دوستدار محيط زيست براي سنتز آريل يديد با استفاده از دي آزودار كردن آمين هاي آروماتيك با استفاده از NaNO2 و نانوسيليكا پريديك اسيد گزارش شده است. اين روش يك روش سبز، دوست دار محيط زيست و فاقد حال براي سنتز آريل يديد مي باشد.

An efficient and environmentally benign method for the synthesis of aryl iodides have been developed by diazotization of aromatic amines with NaNO2 and nanosilica periodic acid (nano-SPIA) as a green catalyst via grinding followed by a sandmeyer iodination by KI under solvent-free conditions at room temperature. The ensuing aryl diazonium salts supported on nano-SPIA were sufficiently stable to be kept at room temperature in the dry state. This method is a novel, efficient, eco-friendly route for solvent-free synthesis of aryl iodides.
