Ghorbani-Choghamarani, Arash; Seydyosefi, Zeinab; Tahmasbi, Bahman published the artcile< Tribromide ion supported on boehmite nanoparticles as a reusable catalyst for organic reactions>, Reference of 699-12-7, the main research area is sulfoxide preparation chemoselective; sulfide sulfoxidation tribromide ion nanocatalyst; dihydroquinazolinone preparation; benzaldehyde anthranilamide condensation tribromide ion nanocatalyst; polyhydroquinoline preparation; dimedone benzaldehyde ethyl acetoacetate ammonium acetate condensation tribromide ion.
Boehmite nanoparticles are not air or moisture sensitive; therefore, they were prepared in water at room temperature using inexpensive materials, without inert atm., by a very simple and inexpensive procedure. When the surface of boehmite nanoparticles was modified by N,N,N’,N’-tetraethyldiethylenetriamine (TEDETA), tribromide ions became immobilized on modified boehmite nanoparticles (Br3-TEDETA@Boehmite). These materials were characterized by Fourier transform IR spectroscopy, thermogravimetric anal., Brunauer-Emmett-Teller, X-ray diffraction, energy-dispersive X-ray spectroscopy, and SEM techniques. Finally, the catalytic activity of Br3-TEDETA@Boehmite was examined in the selective oxidation of sulfides R1SR2 [R1 = Ph, Me, (CH2)2CH3, etc.; R1R2 = -(CH2)4-; R2 = Me, benzyl, (CH2)2OH, etc.] to sulfoxides R1S(O)R2. Besides, the catalytic activity of Br3-TEDETA@Boehmite was extended to the synthesis of organic heterocyclic compounds, such as 2,3-dihydroquinazolin-4(1H)-one I [R3 = 4-Cl, 4-NO2, 3,4-(OMe)2, etc.] and polyhydroquinoline derivatives II [R4 = 2,3-(Cl)2, 3-NO2, 4-OEt, etc.]. This catalyst was reused several times without significant loss of its catalytic efficiency.
