Direct One Pot Synthesis of Iodoarenes from Aromatic Amine Using TCT-Wet.Sio2 as an Effective Heterogeneous Catalyst
Keywords:
Trichlorotriazene, diazonium salt, HClAbstract
The present article described the one pot direct synthesis of structurally diverse aryl iodides from primary aromatic amines in aprotic media. 1,3,5-Trichlorotriazene (TCT)-Wet. SiO2 (50 % W/W) was found to be an effective heterogeneous catalyst for in situ generation of diazonium salt followed by iodination with potassium iodide. The methodology presented here was worked well for the variety of aromatic amines possessing electron donating as well as electron withdrawing substituents on aromatic ring at room temperature. The corresponding aryl iodides are obtained in good to excellent yield.
