Catalytic activity of dicarbonylrhodium complexes of aminobenzoic acid ligands on carbonylation of alcoho
Get PDFRhodium(I) complexes of the type, [Rh(CO)2ClL] (1), where L = 2-aminobenzoic acid (a), 3-aminobenzoic acid (b) and
4-aminobenzoic acid (c), have been synthesised. Oxidative addition (OA) of complexes 1 with electrophiles like RI (R = CH3,
C2H5) produce Rh(III) complexes of the type [Rh(CO)(COCH3)IClL] (2) and [Rh(CO)(COC2H5)IClL] (3). The OA reactions
of complexes 1 with RI follow a two stage kinetics and the observed rate constants are in the order 1b > 1c > 1a irrespective
of stages. The complexes 1 show higher catalytic activity for carbonylation of methanol and ethanol than that of the well
known species [Rh(CO)2I2]−
Voltage characteristics of Ag,Al, Ni - (N)CTDE junction
Get PDFSchottky barriers of Ag, Al, Ni–(n)CdTe structures have been prepared and studied. The films were
prepared by rf sputtering and doped with Cd metal. Diode ideality factor of these junctions are greater than
unity and barrier height varies from 0×6–0×7 eV and are affected by room illumination. Photovoltaic effect of
these junctions was very poor and fill factor below 0×4. Low doping concentration, high defect density, presence
of an interfacial layer and presence of high series resistance are perceived to affect the J–V characte
Potential for Improving pea production by co-inoculation with flourscent Pseudomonous and Rhizobium
Get PDFSeed bacterization with five plant growth promoting fluorescent Pseudomonas strains isolated from Indian and
Swedish soils and three Rhizobium leguminosarum biovar viceae strains isolated from Swedish soils were shown
to promote plant growth in Pisum sativum L. cv. Capella. Co-inoculation of the fluorescent pseudomonads and
Rhizobium improved plant growth in terms of shoot height, root length and dry weight. Both the fluorescent
pseudomonads and Rhizobium were shown to exhibit a wide range of antifungal activity against pathogens specific
to pea. Seed bacterization with plant growth promoting strains alone and together with a rhizobial isolate, R 361-27
reduced the number of infected peas grown in Fusarium oxysporum infested soils. We found that the introduced
organisms were able to colonize the roots, which was confirmed using immunofluorescence staining and drug
resistant mutant strains. In a synthetic culture medium, all the plant growth promoting fluorescent pseudomonads
strains produced siderophores, which shown to express antifungal and antibacterial activity. Our results suggest the
potential use of these bacteria to induce plant growth and disease suppression in sustainable agriculture production

Intersalation reaction of Trisdiimine metal complexes with Montmorganite clay : a new approach
Get PDFMicrowave-Mediated Selective Monotetrahydropyranylation ofSymmetrical Diols Catalyzed by Iodine
Get PDFThermal and spectrodcopic studies on the decomposition of [Ni{di(2-aminoethyl)amine}2] and [Ni(2,2':6',2"-terpyridine)2] Montmorillonite intercalated composites
Get PDFIntercalated [Ni{di(2-aminoethyl)amine}2]-Montmorillonite (I) and [Ni(2,20:60,200-terpyridine)2]-Montmorillonite (II)
composites have been synthesized and their thermal behavior studied by TG, DTG and DTA substantiated by XRD and IR
spectroscopy. Thermal stabilities of the composites I and II were about 50 and 1508C higher, respectively, compared to their
respective free metal complex salts. These results indicate that the metal complex with aromatic backboned ligands had higher
thermal stability than that of the aliphatic one upon intercalation into layered clay. XRD data showed that on heating, the basal
spacing (d001) of the I composite decreased gradually from 14.5
A convenient prepartion of N-acyl-1-aza-1, 3-diene from formylenamide and its utility in Inverse Electron Demand Diels-Alder Reactions
Get PDFSynthesis, characterization and thermal decomposition of M1[M2(C2O4)2].xH2O (x=5 for M1=Co and x=4 for M1=Cd;M2=Ni
Get PDFCobalt bis(oxalato)nickelate pentahydrate, Co[Ni(C2O4)2]×5H2O and cadmium bis(oxalato)nickelate
tetrahydrate, Cd[Ni(C2O4)2]×4H2O have been synthesized and characterized by elemental analysis,
reflectance and IR spectral studies. Thermal decomposition studies (TG, DTG and DTA ) in air
showed that both the compound of cobalt and cadmium produced the oxide, MNiOx (x=3 for M=Co;
x=2 for M=Cd ) at 325 and 360°C respectively. DSC studies in nitrogen attributed only the mixture
of both the metal at the end
