    Two new tetrathiotungstates (pipH2)[WS4] (1) and (trenH2)[WS4] . H2O (2) (pip = piperazine and tren = tris(2-aminoethyl)amine) were synthesized and characterized by elemental analysis, infrared, Raman, UV-Visible and 1H ...
  • Butane-1,4-diammonium tetrathiomolybdate(VI) 
    Srinivasan, B.R.; Naether, C.; Bensch, W. (Acta Crystallographica Section E-Structure Reports Online. 61; 2005; M2454-M2456.)
    The structure of the title complex, (C4N2H14)[MoS4], consists of tetrahedral tetrathiomolybdate dianions connected to butane-1,4-diammonium dications, (1,4-bnH(2))(2+), via hydrogen bonding. The compound contains two ...
  • A concise synthesis of 1-oxygenated carbazole alkaloids, Clausine E and Clausine F 
    Kamat, D.P.; Parsekar, S.B.; Kamat, V.P.; Tilve, S.G. (Synthesis. 46(20); 2014; 2789-2793.)
    A rapid entry into naturally occurring and biologically important 1-oxygenated carbazole clausine E was established through Wittig reaction and annulation. Further O-prenylation of clausine E by Mitsunobu reaction followed ...
  • Thick films of In, Bi and Pd metal oxides impregnated in LaCoO3 perovskite as carbon monoxide sensor 
    Salker, A.V.; Choi, N.J.; Kwak, J.H.; Joo, B.S.; Lee, D.D. (Sensors and Actuators B-Chemical. 106(1); 2005; 461-467.)
    Thick films of LaCoO3 perovskite and metal oxides (In, Bi and Pd) impregnated in LaCoO3 have been used as sensor materials for sensing temperature and carbon monoxide gas. LaCoO3 has shown good characteristics of a thermal ...
  • Carbon xerogel supported Pt and Pt-Ni catalysts for electro-oxidation of methanol in basic medium 
    Samant, P.V.; Fernandes, J.B.; Rangel, C.M.; Figueiredo, J.L. (Catalysis Today. 102; 2005; 173-176.)
    Highly mesoporous carbon was obtained by carbonization of a polymer xerogel previously synthesized via sol-gel condensation of resorcinol and formaldehyde. The investigation describes electro-oxidation of methanol in ...
  • A convenient synthesis of gamma-methyl alpha-(alkylidene)-gamma-butyrolactones 
    Shet, J.B.; Amonkar, C.P.; Nadkarni, V.S.; Tilve, S.G. (Indian Journal of Chemistry Section B-Organic Chemistry Including Medicinal Chemistry. 44(7); 2005; 1505-1508.)
    gamma-Methyl-alpha-(alkylidene substituted)-gamma-butyrolactones have been synthesized in two steps. The anion of allyl phosphonate 1 is condensed with different carbonyl compounds to afford alpha,beta-unsaturated esters ...
  • SO sub(4) sup(2-) ion induced synthesis of manganese oxide octahedral molecular sieves (OMS-2) 
    Rebello, J.S.; Fernandes, J.B. (Microporous and Mesoporous Materials. 77(41673); 2005; 189-192.)
    The investigation reports manganese oxide OMS-2 phase formation induced by sulphate ions unlike the conventional use of the cations K+, Pb2+ or Ba2+. OMS-2 is synthesised by NaClO3 oxidation of Mn(II)SO4 and phase formation ...
  • Carbon supports for methanol oxidation catalyst 
    Samant, P.V.; Rangel, C.M.; Romero, M.H.; Fernandes, J.B.; Figueiredo, J.L. (Journal of Power Sources. 151; 2005; 79-84.)
    Highly mesoporous carbon was synthesized employing conventional sol-gel technique using resorcinol and formaldehyde. The porous carbon electrodes were characterized by X-ray powder diffraction, N-2, adsorption isotherm, ...
  • Ab initio study and its comparison with x-ray crystal structure of 4-[1-(4-chloro-phenylamino)-ethyl]-5-methyl-2-p-tolyl-2,4-dihydro-pyrazol-3-one 
    Jadeja, R.N.; Shirsat, R.N.; Suresh, E. (Structural Chemistry. 16(5); 2005; 515-520.)
    The ab initio calculation of the title compound was carried out at HF as well as DFT level of theory. The full geometry optimization of the ligand was carried out using 6-31G(d) basis set. The results obtained were correlated ...
  • Methylation of phenol over Degussa P25TiO(2) 
    Gandhe, A.R.; Fernandes, J.B. (Journal of Molecular Catalysis A-Chemical. 226(2); 2005; 171-177.)
    Degussa P25 TiO2 was evaluated as a catalyst for vapour phase methylation of phenol. It gave an optimum conversion of 32 percent at 450 degrees C and formed predominantly the ortho-, para- and meta-cresols. The activity ...
