One-pot Efficient Oximation-Beckmann Rearrangement of Ketones Catalyzed by Fe۳O۴ Under Solvent-free Conditions

Fe۳O۴ nanoparticles were employment as an efficient and magnetically separable Nano catalyst for the synthesis of amides via one-pot Beckmann rearrangement of ketones under solvent-free conditions. Various secondary amides were synthesized by this method in moderate to good yields. The catalyst showed high thermal stability and was recovered and reused at least five times without any considerable loss of activity. The present process is environmentally benign and economical
