Activity of pd doped and supported Mn2O3 nanomaterials for CO oxidation

Kunkalekar, R.K.; Salker, A.V. (Reaction Kinetics Mechanisms and Catalysis. 106(2); 2012; 395-405.)

Nanosized Pd doped and supported on Mn2O3 catalysts were prepared and tested for CO oxidation. The introduction of Pd in Mn2O3 enhances the activity for CO oxidation due to a synergistic effect. The supported samples showed ...
Solvent-free synthesis of 4-aryl-3,4-dihydrobenzopyran-2-ones via [3+3] cyclocoupling of phenols with cinnamic acid catalyzed by molecular iodine

Kamat, D.P.; Tilve, S.G.; Kamat, V.P. (Tetrahedron Letters. 53(33); 2012; 4469-4472.)

Molecular iodine was used as a catalyst in the [3+3] cyclocoupling of phenols and cinnamic acids which proceeds via a tandem esterification-hydroarylation process at 120-130 degrees C under solvent-free conditions. Substituted ...
An efficient synthesis of Lactarochromal from 6-amino-2,2-dimethylchroman-4-one

Kamat, V.P.; Asolkar, R.N.; Kirtany, J.K. (Indian Journal of Chemistry Section B-Organic Chemistry Including Medicinal Chemistry. 51(12); 2012; 1761-1762.)

Lactarochromal 1, a metabolite of Lactarius deliciosus, has been synthesised starting from 6-amino-2,2-dimethylchroman-4-one 3, which in turn, is prepared from paracetamol via the known intermediates. The amino compound 3 ...
Synthesis of optically active homotryptophan and its oxygen and sulfur analogues

Goswami, K.; Paul, S.; Bugde, S.T.; Sinha, S. (Tetrahedron. 68(1); 2012; 280-286.)

D-Homotryptophan and its sulfur analogue have been synthesized by Sonogashira coupling between 3-iodoheteroarenes and ethynyloxazolidine followed by reduction of triple bond and oxidation of alcohol to acid. L-Homotryptophan ...
Synthesis and thermal studies of the cobalt zinc ferrous fumarato-hydrazinate a precursor to obtain nanosize ferrites

Gonsalves, L.R.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 871-875.)

Nanosize Co1-x Zn(x)Fe2O4 (x = 0, 0.1, 0.3, and 0.4) have been synthesized by the precursor combustion technique via autocatalytic combustion of the mixed-metal fumarato-hydrazinate precursors. A key feature of these ...
Biogenetic-type synthesis of 2-hydroxy-4,4,7-trimethyl-1(4h)-naphthalenone, a modified apocarotenoid from Ipomoea pes-caprae

Fondekar, K.P.P.; Paknikar, S.K.; Torres, S.; Kamat, S.P. (Natural Product Communications. 7(7); 2012; 827-830.)

A biogenetic-type synthesis of 2-hydroxy-4,4,7-trimethyl-1(4H)-naphthalenone (1), a modified apocarotenoid isolated from Ipomoea pes-caprae (Linn.) R.Br. showing anti-inflammatory activity by inhibiting prostaglandin ...
Synthesis of Bis(indolyl)methanes under catalyst-free and solvent-free conditions

Dhumaskar, K.L.; Tilve, S.G. (Green Chemistry Letters and Reviews. 5(3); 2012; 353-402.)

Condensation of indole with aromatic aldehydes has been carried out without using any catalyst and solvent to give bis(indolyl)methanes.
Synthesis and characterization of ultrafine spinel ferrite obtained by precursor combustion technique

Gonsalves, L.R.; Mojumdar, S.C.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 859-863.)

Nanoparticles of the spinel ferrite, Co0.6Ni0.4Fe2O4 have been synthesized by the precursor combustion technique. This synthetic route makes use of a novel precursor viz., metal fumarato hydrazinate which decomposes ...
Synthesis and characterization of nanosize nickel-doped cobalt ferrite obtained by precursor combustion method

Gonsalves, L.R.; Verenkar, V.M.S. (Journal of Thermal Analysis and Calorimetry. 108(3); 2012; 877-880.)

Nanoparticles of the spinel ferrite, Co1-x Ni(x)Fe2O4 (x = 0, 0.2, 0.3) have been synthesized by the precursor combustion technique. Novel precursors of metal fumarato-hydrazinate have been employed to yield the nanosized ...
Synthesis, purification and thermal behaviour of sulfonated metalloporphyrins

Gokakakar, S.D.; Salker, A.V. (Journal of Thermal Analysis and Calorimetry. 109(3); 2012; 1487-1492.)

A free-base tetra sodium meso-tetra (p-sulphonatophenyl) porphyrin (TPPS4) and its corresponding metalloporphyrins (MTPPS4), where M = Co, Ni and Zn were synthesized and characterized by UV-visible spectroscopy, infra red ...
