WebProcedure for Iodination of Vanillin In your 100 mL round-bottomed flask, place 1.0 g (record what you actually use) of vanillin, 1.2 g of sodium iodide, and 20 mL of methanol. Add a magnetic stir bar, and stir to dissolve the solids. While stirring, cool the flask in an ice-water bath for five minutes. WebIodination of various industrially and pharmaceutically important substituted aromatics has been achieved using N-iodosuccinimide (NIS) in solid state by grinding at room temperature. This method provides several advantages such as short reaction time (5–8 min), high yields (94–99%), and nonhazardous and simple work-up procedure.
