Molaei, Somayeh; Moeini, Nazanin; Ghadermazi, Mohammad published the artcile< Synthesis of CoFe2O4 @Amino glycol/Gd nanocomposite as a high-efficiency and reusable nanocatalyst for green oxidation of sulfides and synthesis of 5-substituted 1H-tetrazoles>, Category: alcohols-buliding-blocks, the main research area is cobalt spinel ferrite magnetite nanoparticles immobilized covalently amino glycol; gadolinium nanocomposite preparation; nickel ferrate magnetite nanoparticles supported on silica immobilized covalently; amino glycol gadolinium nanocomposite preparation; sulfinyl green preparation; tetrazole green preparation.

In this study, a novel gadolinium 2-amino-2-methyl-1,3-propanediol (amino glycol) complex immobilized covalently on CoFe2O4 magnetite nanoparticles was synthesized. The nanocatalyst was characterized thoroughly using thermogravimetric analyzes (TGA), FT-IR spectroscopy, SEM (SEM), energy dispersive X-ray (EDX), inductively coupled plasma optical emission spectroscopy (ICP-OES), vibrational sample magnetometry (VSM), and powder X-ray diffraction (PXRD). CoFe2O4 @amino glycol/Gd was found to be efficient for the oxidation of sulfides to sulfinyl R1S(O)R2 [R1 = Et, Ph, Bn, etc.; R2 = Me, Et, Ph, etc.] and synthesis of 5-substituted 1H-tetrazoles I [R3 = Ph, Bn, 4-HOC6H4, etc.] at mild reaction conditions in the green medium. The influences of reaction temperature, solvent, and the amount of catalysts were studied. The best results were obtained in water and without organic solvent condition for 5-substituted 1H-tetrazoles and oxidation of sulfides, resp. The catalyst was easily collected via an external magnetic field and further reused at least 6 times without a significant decrease in catalytic activity. The wide applicability of the catalyst, ease of catalyst separation, its reusability capacity, and importantly reaction operation in a green medium and elimination of hazardous organic solvents were the advantages of this catalyst.

Davidson, Stuart C.; Gomes, Gabriel dos Passos; Kuhn, Leah R.; Alabugin, Igor V.; Kennedy, Alan R.; Tomkinson, Nicholas C. O. published the artcile< Organocatalytic sulfoxidation>, Safety of 2-(Phenylthio)ethanol, the main research area is sulfide diketone catalyst sulfoxidation kinetics; sulfoxide preparation.

Treatment of a sulfide with a catalytic amount of a 1,3-diketone in the presence of silica sulfuric acid as a co-catalyst and hydrogen peroxide (50% aq) as the stoichiometric oxidant leaded to the corresponding sulfoxide product. The reaction was effective for diaryl, aryl-alkyl and dialkyl sulfides and was tolerant of oxidisable and acid sensitive functional groups. It showed that the tris-peroxide , formed on reaction of pentane-2,4-dione with hydrogen peroxide under acidic reaction conditions, it oxidised two equivalent of sulfide using the exocyclic peroxide groups whereas the endocyclic peroxide remained intact. Calculations provided a mechanism consistent with exptl. observations and suggested the reaction proceeded via an initial acid catalyzed ring opening of a protonated tris-peroxide prior to oxygen transfer to a sulfur nucleophile.

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.

Kundu, Bidyut Kumar; Das, Mriganka; Ganguly, Rakesh; Bhobe, Preeti A.; Mukhopadhyay, Suman published the artcile< Role of zeolite encapsulated Cu(II) complexes in electron transfer as well as peroxy radical intermediates formation during oxidation of thioanisole>, Name: 2-(Phenylthio)ethanol, the main research area is copper complex encapsulated zeolite sulfoxidation catalyst; electron transfer copper complex encapsulated zeolite sulfoxidation catalyst; peroxy radical copper complex encapsulated zeolite sulfoxidation catalyst.

Zeolite encapsulated host-guest complexes [CuL(NO3)@Y], and [CuL2@Y] (where, HL is 1-[(3-dimethylamino-2,2-dimethyl-propylimino)-methyl]-naphthalen-2-ol, I) have been synthesized and characterized by XRD, FTIR, Raman, TEM, XPS, UV-DRS, BET, EXAFS, and EPR spectroscopy. These complexes were used as heterogeneous catalysts for the oxidation of thioanisole, di-Ph sulfide, and 2-phenylthioanisole to produce sulfoxides analogs. H2O2 shows superior conversion efficiency and product selectivity over other common oxidants, viz tert-Bu hydroperoxide (TBHP), urea hydrogen peroxide (UHP) and di-tert-Bu hydroperoxide (DTBP). Formation of thermally stable copper hydroperoxo intermediate, which is to be believed as rate determining step in past few years, has been well proven. Besides that, for the first time, we have established that the oxidation process is not only going through by the generation of Cu(II)-OOH species but there is a considerable role of electron transfer (ET) mechanism also. Further, better TON value and recyclability make the encapsuled heterogeneous complexes more useful than that of homogeneous analogs.

In this current study we report the implementation of Mn(IV) grafted multipyridine linked melanine functionalized SBA-15/CCPy/Mn(OAc)2 as a novel high surface area nanocatalyst. The melamine linked multipyridine ligand was introduced over mesoporous SBA-15 to ensure the strong chelation of Mn(OAc)2 in order to deploy as active site. The structural features of the so designed material were properly analyzed with SEM, TEM, EDX, ICP-AES and N2 adsorption-desorption isotherm techniques. Catalytic behavior of the nanocomposite was investigated in the chemoselective oxidation of sulfides to sulfoxides using H2O2 as a mild oxidant under solvent-free conditions at room temperature resulting very good yields. The catalyst was reused up to 8 consecutive cycles without significant leaching and reduced catalytic performance.
