Liquid-crystalline fullerene-ferrocene dyads
(Royal Soc Chemistry, Cambridge, 2004)
The 1,3-dipolar cycloaddition reaction was used to assemble fullerene, ferrocene and a second-generation liquid-crystalline cyanobiphenyl-based dendrimer. The targeted compound displayed an enantiotropic smectic A phase ...
Density functional theory study of the magnetic coupling interaction in a series of binuclear oxalate complexes
(Springer Wien, Wien, 2012)
Magnetic couplings in oxalate-bridged binuclear complexes, namely five isomers of [(VO)(2)(ox)(SCN)(6)](4-), trans-(equatorial, equatorial), cis-(equatorial, equatorial), trans-(axial, axial), cis-(axial, axial), and (axial, ...
Hydrophilic Interaction Planar Chromatography of Geometrical Isomers of Selected Co(Iii) Complexes
(Taylor & Francis Inc, Philadelphia, 2012)
The retention behavior of fourteen geometrically isomeric Co(III) complexes: three pairs of neutral facial-meridional (fac-mer) isomers, one pair of cis-trans isomeric complexes of neutral type, and three pairs of cationic ...
Improved procedure for the preparation of cis-2,4-dimethylglutaranhydride
(Taylor & Francis Inc, Philadelphia, 2006)
Addition of 2.5 mol% DBU to a mixture of isomeric 2,4-dimethylglutaric anhydrides in ethyl acetate promotes crystallization-induced transformation, affording the pure cis-2,4-dimethylglutaric anhydride in 87% yield.
Liquid-crystalline bisadducts of [60]fullerene
(Amer Chemical Soc, Washington, 2006)
A second-generation cyanobiphenyl-based dendrimer was used as a liquid-crystalline promoter to synthesize mesomorphic bisadducts of [60]fullerene. Liquid-crystalline trans-2, trans-3, and equatorial bisadducts were obtained ...
3D electrogenerated chemiluminescence: from surface-confined reactions to bulk emission
(Royal Soc Chemistry, Cambridge, 2015)
Among luminescence techniques, electrogenerated chemiluminescence (ECL) provides a unique level of manipulation of the luminescent process by controlling the electrochemical trigger. Despite its attractiveness, ECL is by ...
Radical, one-step approach to o-chlorophenyl thioethers from xanthates. A rapid access to vinylsilanes
(Amer Chemical Soc, Washington, 2008)
Xanthates have been readily converted into o-chlorophenyl thioethers using a one-step procedure conducted under radical conditions. In some selected cases, these aryl thioethers were successfully oxidized to the corresponding ...
A convenient procedure for the preparation of Garner's aldehyde
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The palladium/silane reduction of a serine thioester derivative allows for the preparation of enantiomerically pure Garner's aldehyde from serine, in gram quantities within 24 h.
Cyclohexane oxidation and cyclohexyl hydroperoxide decomposition by poly(4-vinylpyridine-co-divinylbenzene) supported cobalt and chromium complexes
(Elsevier Science Sa, Lausanne, 2010)
Polymer supported catalysts with Co(II) and Cr(VI) ions were prepared and characterized by means of FTIR, diffuse reflectance UV-vis, nitrogen physisorption, mercury porosimetry and SEM-EDX measurements. The catalytic ...
DFT study of the Jahn-Teller effect in Cu(II) chelate complexes
(Elsevier Science Bv, Amsterdam, 2010)
Density functional theory (DFT) in conjunction with the intrinsic distortion path (IDP) is employed to study the Jahn-Teller (JT) effect in all four diastereoisomers of tris(ethylenediamine)copper(II) ([Cu(en)(3)](2+)) and ...
