Addn. of 4-tert-butylpyridine (4TBP) to redox electrolytes used in dye-sensitized TiO2 solar cells has a large effect on their performance. In an electrolyte contg. 0.7M LiI and 0.05M I2 in 3-methoxypropionitrile, addn. of 0.5M 4TBP gave an increase of the ...
The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
A general one-step strategy is developed for the synthesis of hexofuranosyl 1-phosphates starting from new unprotected glycofuranosyl donors. It required first the preparation of new 1-thiohexofuranosides bearing a thioimidoyl heterocycle as a leaving grou ...
The following chapter summarizes the various methodologies allowing the reductive cleavage of various carbon---hetereroatom single bonds or multiple bonds naming the transformation of C---N bond, C---P, C---As, C---Sb, C---Bi, C---C, C---Si, C---Ge, C---B, ...
The ligand N,N'-bis[6-carboxy-2-pyridylmethyl]ethylenediamine-N,N'-diacetic acid (H4bpeda) was synthesized using an improved procedure which requires a reduced no. of steps and leads to a higher yield with respect to the published procedure. It was obtaine ...
Based on the ligand LAB the new heterobitopic ligands LAB2, LAB3, LAB4 and LAB5 have been designed and synthesised. The five ligands were designed to selectively form heterobimetallic complexes of composition LnLn'(L)36 when reacted with a pair of ...
The Diels-Alder reaction between cyclopentadiene and methyl acrylate in ionic liquids has been studied in detail. The effect of contamination of the ionic liquids by common impurities, viz. sodium and chloride ions, and water, on the selectivity has been i ...
Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetrame ...
Liquid composite moulding of Lactam 12 monomer and activating system (APLC12) into satin weave carbon fabrics is investigated, with emphasis on minimising the void content in the final part. The main sources for void formation are identified. The solidific ...
