Ultrasound-Mediated Synthesis of 2,4,6-Triaryl-Pyridines Using MgAl2O4 Nanostructures

Nanocrystalline MgAl 2 O 4 was found to be a highly efficient catalyst for the preparation of 2,4,6-triaryl-pyridines from the reaction of acetophenone derivatives, aryl aldehydes, and ammonium acetate under sonic condition for the first time. The present methodology offers several advantages, such...

Description
Summary:Nanocrystalline MgAl 2 O 4 was found to be a highly efficient catalyst for the preparation of 2,4,6-triaryl-pyridines from the reaction of acetophenone derivatives, aryl aldehydes, and ammonium acetate under sonic condition for the first time. The present methodology offers several advantages, such as excellent yields, simple procedure, shorter reaction times, and milder conditions; the catalyst also exhibited remarkable reusable activity. This procedure is much simpler and faster than the protocols published to date.
