    AbstractIodination 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.
