Spectroscopic Characterization of Some Tetradentate Schiff Bases and Their Complexes with Nickel, Copper and Zinc
Tập 48 Số 2 - Trang 153-158 - 2001
AbstractThree ligands have been formed by the 1:2 molar condensation of
o‐phenylenediamine with salicyldhyde, 2‐hydroxy‐1‐naphthaldhyde or
o‐hydroxyacetophenone. The potentially tetradentate ligands are
N,N′‐bis(salicyldhyde)‐o‐phenylenediamine(SalophH2),
N,N′‐bis(2‐hydroxy‐1‐naphthaldhyde)‐o‐phenylenediamine (NophH2) and
N,N′‐bis(o‐hydroxyacetophenone)‐o‐phenylenediamine (AophH2), respectively. T...
A review of transition metal‐based bifunctional oxygen electrocatalysts
Tập 66 Số 8 - Trang 829-865 - 2019
AbstractElectrochemical energy storage and conversion devices play a key role in
the development of clean, sustainable, and efficient energy systems to meet the
sustainable growth of our society. However, challenging issues including the
sluggish kinetics of oxygen electrode reactions involving the oxygen reduction
reaction (ORR) and the oxygen evolution reaction (OER) are present, limiting the
im...
A Journey of Metal‐metal Bonding beyond Cotton's Quadruple Bonds
Tập 61 Số 1 - Trang 9-26 - 2014
AbstractWhereas the study of the Cotton's quadruple bonding between two metal
atoms has been mature, exploration of bonding, potential applications and
reactivity in linear oligonuclear metal complexes and quintuple bonded dinuclear
compounds is currently underway. Stabilized by four long‐chain organic ligands
containing various numbers (3‐13) of nitrogen donors, many metal string
complexes featur...
Development of a Novel Hybrid Immobilization Material (HY‐IM) for Fermentative Biohydrogen Production from Beverage Wastewater
Tập 61 Số 7 - Trang 827-830 - 2014
AbstractA novel material (hybrid immobilization material, HY‐IM) was developed
by the combination of calcium‐alginate, activated carbon (prepared from de‐oiled
jatropha waste), wako gel (silica gel) and chitosan for immobilization of
hydrogen‐producing bacteria. The stability of the prepared immobilized cells was
evaluated by ten repetitive batch experimental runs; the cumulative hydrogen
producti...
Ultrasound‐Assisted One‐Pot Synthesis of Octahydroquinazolinone Derivatives Catalyzed by Acidic Ionic Liquid [Tbmim]Cl2/AlCl3
Tập 57 Số 1 - Trang 89-92 - 2010
AbstractAcidic ionic liquid [tbmim]Cl2/AlCl3 catalysed an efficient synthesis of
octahydroquinazolinone derivatives under ultrasound‐irradiation. This method
provides several advantages such as environment benign, high yields and simple
work‐up procedure.
Applications of Highly Sulfated Cyclodextrins for Enantiomeric Separation by Capillary Electrophoresis
Tập 46 Số 5 - Trang 847-860 - 1999
AbstractSeparation of enantiomeric pairs of compounds by capillary
electrophoresis (CE) was performed using highly sulfated α‐, β‐ and
γ‐cyclodextrins (HS‐CDs). CE analysis of the HS‐CDs using indirect absorbance
detection showed that the new class of chiral selectors has substantially higher
degrees of sulfation and narrower heterogeneity than those used in previous
reports. Elemental analyses sh...
Hypervalent Iodine(III) Sulfonate Mediated Synthesis of Quinoxalines in Liquid PEG‐400
Tập 56 Số 4 - Trang 683-687 - 2009
AbstractPEG‐400[poly(ethylene glycol‐400)] is used as a “green” recyclable
solvent in the one‐pot synthesis of quinoxalines by reaction with aryl ketones,
hypervalent Iodine(III) Sulfonate, and o‐phenylenediamines. Significant rate
enhancements and improved yields have been observed.
Ionic Liquid as an Efficient Promoting Medium for Synthesis of Bis‐Pyrazolo[3,4‐b:4′,3′‐e]Pyridines
Tập 55 Số 4 - Trang 755-760 - 2008
AbstractThe preparation of a series of bis‐pyrazolo[3,4‐b:4′,3′‐e]pyridines by
the reaction of 5‐aminopyrazole with aldehydes in ionic liquid [bmim]Br is
described. This new method has the advantages of easier work‐up, milder reaction
conditions, high yields and environmental friendliness compared with other
methods.
The Isolation and Determination of Sulforaphane from Broccoli Tissues by Reverse Phase‐High Performance Liquid Chromatography
Tập 58 Số 7 - Trang 906-910 - 2011
AbstractSulforaphane is a cognate isothiocyanate of glucoraphanin, released by
degradation of glucosinolate through myrosinase enzyme, when Brassica tissues
are crushed or chewed. C8 analytical column and mixture of water/acetonitrile
65/35 (ν/ν) as mobile phase were used to separate sulforaphane in broccoli
tissues (e.g., 7‐day‐seedling, seed, floret and leave). Confirmation of
sulforaphane in cr...
Constituents of the Heartwood of Diospyros Eriantha
Tập 41 Số 2 - Trang 195-198 - 1994
AbstractThe isolation and identification of fifteen compounds from the heartwood
of Diospyros eriantha are described. Their structures were determined on the
basis of spectral evidence and/or comparison with authentic samples. These
compounds include three steroids (stigmast‐4‐en‐3‐one, stigmast‐4‐ene‐3,6‐dione,
and 3β‐hydroxystigmast‐5‐en‐7‐one), seven triterpenoids (friedelin, lupeol,
betulinald...
