times and high yields. A highly efficient and green protocol is reported for the reductive deoxygenation of organic epoxides to olefins usingtin(II) chloride/sodium iodide as a novel reagent. The reaction gives an excellent yield (85–96%) in ethanol under reflux within 2–10 minutes, without affecting other functional groups. The advantages of our method are the use of inexpensive reagents, the eco-friendly
