One-pot aromatic bromination-rearrangement catalyzed by GaCl3

One-pot Efficient Oximation-Beckmann Rearrangement of Ketones Catalyzed by Fe3O4 Under Solvent-free Conditions

Fe3O4 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 considerab...

Mesolite catalyzed one pot synthesis of quinoline-3-carbonitrile derivatives

Natural mesolite type zeolite was collected, modified by sulfuric acid treatment and characterized by using Powder-X ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR).Temperature programmed ammonia desorption (NH3-TPD), Brunauer-Emmer-Teller (BET) surface area analysis.  Modified dealuminat...

Cyanation and bromination of electron-rich aromatics by BrCN under solvent-free conditions catalyzed by AlCl3: A new examples of Beckmann-type rearrangement

A convenient route for cyanation and bromination of some electron-rich aromatics (anisole, 1,3-dimethoxybenzene, 1,4-dimethoxybenzene, 1,3,5-trimethoxybenzene and β-naphthol) by BrCN in the presence of aluminum trichloride (AlCl3), as catalyst, by grinding method under solvent-free conditions at room temperature to 60 °C was described in good yield. The structures of all obtained products were ...
