An Efficient Protocol for the Eliminative Deoxygenation of Aliphatic and Aromatic Epoxides to Olefins with Polyphosphoric Acid as a Promoter.
ChemInform(2016)
摘要
Abstract An efficient eliminative deoxygenation reaction is reported for the conversion of aliphatic and aromatic epoxides to olefins. Polyphosphoric acid (PPA) is used in 30 mol % as a promoter to afford the products in excellent yield (85–96%) at 50 °C under neat condition. Our method has advantages such as inexpensive reagents, high yield, stereoselective product in short reaction time under eco-friendly reaction conditions.
