Cernak, Juraj published the artcileField induced slow magnetic relaxation in a zig-zag chain-like Dy(III) complex with the ligand o-phenylenedioxydiacetato, SDS of cas: 5411-14-3, the publication is New Journal of Chemistry (2020), 44(31), 13458-13465, database is CAplus.

The new complex [Dy(PDOA)(NO₃)(H₂O)₂]_n¡¤nH₂O (1) (H₂PDOA is o-phenylenedioxydiacetic acid) was isolated from the reaction of dysprosium(III) nitrate and H₂PDOA in a 1:1 molar ratio. Its crystal structure is formed of neutral zigzag chains in which the nonacoordinated Dy(III) atoms (O₉ donor set) are linked by PDOA ligands with a chelating-bridging coordination mode. DC and AC magnetic studies revealed that 1 behaves as a field-induced SMM with three relaxation channels. The derived values, considering the Orbach relaxation process, of the barrier to spin reversal and the extrapolated relaxation time are U/k_B = 59.5 K and ¦Ó₀ = 6.3 ¡Á 10^-10 s, resp. Ab initio calculations support the exptl. results.

Cernak, Juraj published the artcileSyntheses, crystal structure and magnetocaloric effect of [Gd(PDOA)(NO₃)(H₂O)₂]_n, Recommanded Product: 2,2-(1,2-Phenylenebis(oxy))diacetic acid, the publication is Journal of Molecular Structure (2017), 179-185, database is CAplus.

The coordination polymer [Gd(PDOA)(NO₃)(H₂O)₂]_n (1) (PDOA = o-phenylenedioxydiacetato) has been prepared and spectroscopically and structurally characterized. Its crystal structure is formed of a ribbon-like arrangement of Gd(III) atoms linked by bridging carboxylate groups and placed at the cusps of fused triangles with Gd¡¤¡¤¡¤Gd distances of ?6.1 ?. The Gd(III) central atoms exhibit decacoordination by oxygen atoms from hexadentate PDOA ligands with chelating and bridging functions, a chelating nitrato ligand and two aqua ligands. Intra- and intermol. hydrogen bonds of the O-H¡¤¡¤¡¤O and C-H¡¤¡¤¡¤O types contribute to the stability of the structure. The temperature dependence of the magnetic susceptibility revealed weak magnetic interactions among Gd(III) ions which may be attributed to dipolar coupling. Investigation of the magnetocaloric effect gives an estimate of the maximum value of isothermal change of magnetic entropy -¦¤S_m ¡Ö 35 J kg^-1 K^-1 which suggests that 1 can be a good material for magnetic cooling at low temperatures

Yang, Wenqian published the artcileThe First Fluorescent Diboronic Acid Sensor Specific for Hepatocellular Carcinoma Cells Expressing Sialyl Lewis X, Synthetic Route of 5411-14-3, the publication is Chemistry & Biology (2004), 11(4), 439-448, database is CAplus and MEDLINE.

Carbohydrate antigens with subterminal fucosylation have been implicated in the development and progression of several cancers, including hepatocellular carcinoma (HCC). Fluorescent sensors targeting fucosylated carbohydrate antigens could potentially be used for diagnostic and other applications. The authors have designed and synthesized a series of 26 diboronic acid compounds as potential fluorescent sensors for such carbohydrates. Among these compounds, 7q was able to fluorescently label cells expressing high levels of sLex (HEPG2) within a concentration range of 0.5 to 10 ¦ÌM. This compound (7q) did not label cells expressing Lewis Y (HEP3B), nor cells without fucosylated antigens (COS7). This represents the first example of a fluorescent compound labeling cells based on cell surface carbohydrate structures.

Behrsing, Thomas published the artcileHydrated Rare Earth Structural Networks containing the Phenylene-1,2-dioxydiacetate (PDDA) Ligand, Synthetic Route of 5411-14-3, the publication is Zeitschrift fuer Anorganische und Allgemeine Chemie (2013), 639(1), 41-48, database is CAplus.

Reaction of LnCl₃ with Na₂(PDDA) (PDDA = phenylene-1,2-dioxydiacetate) in a 1 to 2 mol ratio in aqueous solution yielded [Ln₂(PDDA)₃(H₂O)₆]¡¤2H₂O, structurally characterized for Ln = Ce (1), Sm (2) (redetn.), Tb (3) and Y (4) in a monoclinic C2/c array, a second related structural form [orthorhombic, Pbcn] being obtained for Tb (5), Ho (6) and Er (7). The ‘domains of existence’ of these two previously described forms are now extended to Ce-Dy, Y, and Eu-Er, resp. Reaction under the same conditions for the heavier Yb³⁺ ion yielded [Yb₂(PDDA)₃(H₂O)₆]_(¡Þ|¡Þ)¡¤4H₂O (8), orthorhombic, Pbca. In the case of Ln = La the bimetallic species [NaLa(PDDA)₂(H₂O)₂]_(¡Þ|¡Þ)¡¤4H₂O (9) was obtained, while reaction of LnCl₃ with Na₂(PDDA) in a 1 to 3 mol ratio led to the isolation of the isotypic (monoclinic, P2₁/c) [NaLn(PDDA)₂(H₂O)₂]_(¡Þ|¡Þ)¡¤4H₂O for Ln = Ce (10) and Sm (12). With the smaller Ln = Yb, the more definitively bimetallic [NaYb(PDDA)₂(H₂O)₂]_(¡Þ|¡Þ)¡¤3H₂O (13) (triclinic, P1?) was obtained, the trihydrate solvation ascribed differing from that recorded (dihydrate) in a cosynchronous report.

The synthesis of mols. bearing (trifluoromethylselenyl)methylchalcogenyl groups ArXCH₂COOH (Ar = 4-methylphenyl, 2-methoxy-4-(prop-2-en-1-yl)phenyl, naphthalen-1-yl, etc.; X = O, S, Se) via an efficient two-step strategy based on a metal-free photoredox catalyzed decarboxylative trifluoromethylselenolation with good yields up to 88%, which raised to 98% in flow chem. conditions was described. The flow methods allowed also to scale up the reaction. The mechanism of this key reaction was studied. The physicochem. characterization of these emerging groups was performed by determining their Hansch-Leo lipophilicity parameters with high values up to 2.24. This reaction was also extended to perfluoroalkylselenolation with yields up to 95%. Finally, this method was successfully applied to the functionalization of relevant bioactive mols. such as tocopherol I or estrone derivatives II (R¹ = CF₃, C₆F₁₃).

Rajesh published the artcileManganese complexes of bis-benzimidazolyl ligand as novel quenchers of superoxide radical anion, Category: catalysis-chemistry, the publication is Polyhedron (1997), 16(20), 3511-3517, database is CAplus.

Mn^II/Mn^III complexes [Mn(DGB)X₂]^0/+ and [Mn(BBB)₂X]²⁺ were synthesized utilizing an exogenous anionic ligand (X = OAc, SCN) with tridentate bis(2-benzimidazolylmethyl)ether (DGB) and bidentate 1,2-bis(2-benzimidazolyloxamethyl)benzene (BBB) ligands. The visible spectra of the Mn^III compounds suggests pseudo C_4v symmetry, and the EPR data on the Mn^II complexes indicates a similar geometry. Cyclic-voltammetric studies reveal that the E_1/2 for the Mn^II/Mn^III couple shifts to a pos. value with acetate as an anionic ligand, implying that this anion stabilizes the Mn^II oxidation state while the E_1/2 data for SCN reveals that the anion stabilizes the Mn^III state. The reoxidation step of the superoxide formed in the cyclic-voltammetric experiments becomes irreversible in the presence of Mn complexes; suggesting that these complexes act as good quenchers for superoxide anion.
