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

Nanocrystalline MgAl2O4 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.

Mesoporous nanocrystalline MgAl2O4: A new heterogeneous catalyst for the synthesis of 2,4,6-triarylpyridines under solvent-free conditions

In this paper, one-pot synthesis of 2,4,6-triarylpyridine by condensation of subsisted acetophenone (II), aromatic aldehydes (I), and ammonium acetate (III) in the presence of nanocrystalline MgAl2O4 as a new heterogeneous catalyst under solvent-free conditions is reported. Advantages of this method are the use of spatially-hindered aldehydes such as 2-methoxy-, 2-fluoro-, and 2-chlorobenzaldehydes, a new nanocatalyst with high surface area, shorter reaction time, easier workup, higher yield, and its environmental friendliness. The performance of this reaction under solvent free conditions using heterogeneous catalysts like MgAl2O4 could enhance its efficiency from an economic as well as green chemistry point of view.

Synthesis of Some New 2,4,6-Triarylpyridines Using Phenacylidenedimethylsulfuranes

Phenacylidenedimethylsulfurane and p-chlorophenacylidenedimethylsulfurane were reacted with α,β-unsaturated ketones in the presence of ammonium acetate in glacial acetic acid to give 2,4,6-triarylpyridines in 45-70percent yields.The structures of the pyri
