The mechanism of the enantioselective hydrosilylation of styrene catalyzed by Pd0 species generated in situ from dichloro[1-[(R)-1-[(S)-2(diphenylphosphino-kP)ferrocenyl]ethyl]-3-trimethylphenyl-5-1H-pyrazole-kN]palladium (1) was investigated in detail thr ...
As part of a case study, rational strategies for the prepn. of all ten 2-, 3-, or 4-pyridinecarboxylic acids and all nine 2-, 3-, 4-, or 8-quinolinecarboxylic acids bearing trifluoromethyl substituents at the 2-, 3-, or 4-position were elaborated. The trif ...
The soln. structure of the two intimate ion pairs present in soln. for [PtMe(h2-olefin)(a-diimine)]BF4 compds. (1-3, shown as I.BF4, R = Ph, 4-MeC6H4, 4-CF3C6H4) their relative abundance and the consequent thermodn. equil. parameters were detd. by a quant. ...
The novel hydroxyquinoline-containing tetrapodal ligand forms water soluble and stable chelates and is a good sensitizer of the NIR luminescence of its NdIII and YbIII complexes; its easy synthesis opens the way for potential biomedical applications. ...
Chloro- and hydrido-complexes of ruthenium(II) with potassium (4-diphenylphosphino)benzenesulfonate (pTPPMS) were prepared and their properties were compared with those of the related complexes of (3-diphenylphosphino)benzenesulfonates. An X-ray crystal st ...
A novel chem. has been developed for the prodn. of capsules composed of a hydrophobic liq. core surrounded by a cross-linked polyacrylamide/alginate membrane. These liq.-core capsules may be used in capsular perstraction for the removal of inhibitory produ ...
Highly selective oxidation of an AlInN interlayer buried in a GaN matrix is demonstrated. This technique was successfully applied to form current apertures in III-nitride light-emitting diodes (LEDs). GaN LEDs were grown by metal-organic vapor phase epitax ...
The reaction of half-sandwich complexes of ruthenium, rhodium, and iridium with amino-substituted 3-hydroxy-2-pyridone ligands in aqueous solution gives monomeric O,O'-chelate complexes. Upon addition of base, the complexes assemble to form trimeric metall ...
To better understand the relationship between lead speciation and bioavailability in natural freshwaters, the interaction of lead with the freshwater alga Chlorella kesslerii was studied in the presence of Suwannee River fulvic acid (SRFA). Special attenti ...
n a previous paper, we reported the first longitudinally detected electron paramagnetic resonance (LODEPR) measurements of fast T1e values in aqueous solutions of two Gd3+ chelates, and we included predicted values for these relaxation times, based on zero ...
