A Convenient Nucleophilic Iodinating Reagent
Typical Procedure: Iodination of 2-(4-methylphenyl)ethanol
A solution of 2-(4-methylphenyl)ethanol (102 mg, 0.75 mmol) in toluene (3.5 mL) is heated to 85 °C. 1 (260 mg, 1.12 mmol) and imidazole (25 mg, 0.37 mmol) are added and the mixture is stirred at 85 °C for 90 min. After cooling to room temperature, the reaction mixture is concentrated in vacuo to afford the crude product. Purification by flash chromatography (SiO2; petrol) affords 1-iodo-2-(4-methylphenyl)ethane as a colorless oil (170 mg, Y. 92%).
