Abstract

A convenient and rapid one-pot method for the synthesis of iodoarenes is developed which involves the sequential diazotization-iodination of aromatic amines with sodium nitrite, silica sulfuric acid and potassium iodide under solvent-free conditions at room temperature. Various aromatic amines possessing electron-withdrawing groups or electron-donating groups are converted into the corresponding aryl iodides in good yields.

Key words

diazotization-iodination - aromatic amines - iodoarenes - silica sulfuric acid
