A furan-based water soluble fluorescent probe (E)-N′-(2,4-dihydroxybenzylidene)furan-2-carbohydrazide (DBF) has been synthesized and characterized by 1H NMR, 13C NMR, ESI-mass spectroscopy and single crystal X-ray diffraction techniques. The synthesized probe exhibits a “”turn-on”” fluorescence response towards Al3+ in Tris-HCl buffer (10 mM) with no significant interference from other metal ions. The strong fluorescence in the presence of Al3+ is attributed to the CHEF (chelation enhanced fluorescence), inhibition of PET (photo-induced electron transfer) and C=N isomerization. 1 : 1 stoichiometric ratio between DBF and Al3+ was rationalized by Job′s plot. Binding constant and LOD were calculated to be 1.031×105 M-1 and 6.34×10-8 M, resp. MTT assay on live A549 cells indicated no serious cytotoxicity in the cells even at higher concentration Further, DBF was successfully used for the detection of accumulated Al3+ in the cytoplasm of cells.

Author is Thuery, Pierre; Atoini, Youssef; Harrowfield, Jack.

Cis-1,2-Cyclohexanedicarboxylic acid (c-chdcH2) was reacted with uranyl nitrate under (solvo-)hydrothermal conditions in the presence of different possible counterions. Two neutral complexes of 1:1 stoichiometry were obtained, [UO2(c-chdc)(DMF)] (1) and [UO2(c-chdc)(H2O)] (2), which crystallize as two-dimensional coordination polymers and do not include the addnl. cations present in solution In contrast, the complex [NH4][PPh4][(UO2)8(c-chdc)9(H2O)6]•3H2O (3) crystallized in the presence of PPh4Br, ammonium cations being generated in situ from acetonitrile hydrolysis. This complex of 8:9 uranium:ligand stoichiometry contains an octanuclear anionic cage of D3 symmetry with a pseudo-cubic arrangement of uranium atoms. The ammonium cation is held within the cage through four hydrogen bonds with uranyl oxo groups directed inwards. This cage complex is luminescent, although with a low quantum yield of 0.06, indicating some potential as a photo-oxidant of included species.

A new fluorescent chemosensor (I) based on salicylaldehyde hydrazide was facilely synthesized through one-step reaction, which exhibited turn-on fluorescent response to Al(III) with 18-fold fluorescence enhancement in aqueous solution at pH 5.5. The binding stoichiometry of 1 toward Al(III) was in 1:1. High selectivity and sensitivity to Al(III) were achieved, which featured a detection limit of 67 nmol L-1 and a linear rang of 1-10 μmol L-1. More importantly, the sensing process could be also performed on solid test paper. After the addition of Al(III), a significant emission color change from yellow to cyan was observed by naked eye due to the intrinsic aggregation-induced emission (AIE) characteristic of 1.

If you want to learn more about this compound(Methyl tetrahydrofuran-2-carboxylate)Electric Literature of C6H10O3, you may wish to communicate with the author of the article,or consult the relevant literature related to this compound(37443-42-8).

Electric Literature of C6H10O3. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Methyl tetrahydrofuran-2-carboxylate, is researched, Molecular C6H10O3, CAS is 37443-42-8, about Low Temperature Chlorine-Initiated Oxidation of Small-Chain Methyl Esters: Quantification of Chain-Terminating HO2-Elimination Channels. Author is Muller, Giel; Scheer, Adam; Osborn, David L.; Taatjes, Craig A.; Meloni, Giovanni.

Cl-initiated oxidation reactions of three small-chain Me esters, Me propanoate (CH3CH2COOCH3; MP), Me butanoate (CH3CH2CH2COOCH3; MB), and Me valerate (CH3CH2CH2CH2COOCH3; MV), are studied at 1 or 8 Torr and 550 and 650 K. Products are monitored as a function of mass, time, and photoionization energy using multiplexed photoionization mass spectrometry coupled to tunable synchrotron photoionization radiation. Pulsed photolysis of mol. chlorine is the source of Cl radicals, which remove an H atom from the ester, forming a free radical. In each case, after addition of O2 to the initial radicals, chain-terminating HO2-elimination reactions are observed to be important. Branching ratios among competing HO2-elimination channels are determined via absolute photoionization spectra of the unsaturated Me ester coproducts. At 550 K, HO2-elimination is observed to be selective, resulting in nearly exclusive production of the conjugated Me ester coproducts, Me propenoate, methyl-2-butenoate, and methyl-2-pentenoate, resp. However, in MV, upon raising the temperature to 650 K, other HO2-elimination pathways are observed that yield Me 3-pentenoate and Me 4-pentenoate. In each Me ester oxidation reaction, a peak is observed at a mass consistent with cyclic ether formation, indicating chain-propagating OH loss/ring formation pathways via QOOH intermediates. Evidence is observed for the participation of resonance-stabilized QOOH in the most prominent cyclic ether pathways. Stationary point energies for HO2-elimination pathways and select cyclic ether formation channels are calculated at the CBS-QB3 level of theory and assist in the assignment of reaction pathways and final products.

The utility of this chiral phosphoric acid is demonstrated by a highly enantioselective (ee up to >99 %) and diastereoselective (syn/anti up to >99:1) asym. Mukaiyama-Mannich reaction of imines with a wide range of ketene silyl acetals. Moreover, this method was successfully applied to the construction of vicinal tertiary and quaternary stereogenic centers with excellent diastereo- and enantioselectivity.

Little discovery in the laboratory: a new route for 610-09-3

Here is a brief introduction to this compound(610-09-3)Electric Literature of C8H12O4, if you want to know about other compounds related to this compound(610-09-3), you can read my other articles.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Organic Chemistry called Hunsdiecker reaction of silver salts of cis- and trans-1,2-cyclohexanedicarboxylic acid, Author is Abell, Paul I., which mentions a compound: 610-09-3, SMILESS is O=C([C@H]1[C@@H](C(O)=O)CCCC1)O, Molecular C8H12O4, Electric Literature of C8H12O4.

Decarboxylation of the Ag salts of cis- and trans-1,2-cyclohexanedicarboxylic acids (I, Ia) by the action of halogen according to Hunsdiecker, et al. (C.A. 38, 374), gave only trans-1,2-dibromocyclohexane (IIa) through isomerization which appeared to take place at an intermediate stage in the reaction. Com. cis-1,2-cyclohexanedicarboxylic anhydride hydrolyzed in boiling H2O gave I, m. 191-4°, isomerized by heating 8 hrs. at 170-80° with a small amount of dilute HCl in a sealed tube to yield 61.5% Ia, m. 228.5-30.5° (from EtOH). Carefully neutralized solutions of the Na salts of I and Ia treated with an exactly equivalent quantity of aqueous AgNO3 and filtered, the precipitate carefully washed with H2O, alc., and Et2O, dried several days over P2O5 in vacuo, and screened to 100 mesh gave Ag salts (III, IIIa) suitable for reaction with Br. Reaction of III and IIIa with Br was carried out at various temperatures by the inverse addition procedure of Conly (C.A. 48, 2561b) in which the dry III or IIIa was added to Br in CCl4, in an apparatus in which the speed and extent of the reaction were followed by observation of the CO2 evolved. The products of the reaction were tabulated (Ag salt, temperature of reaction, % yield, m.p. IIa, n25D, and structure as shown by infrared spectrum given): III, 0-25°, 43, -4.8°, 1.5503, all trans; III, reflux, 47, -4.7°, 1.5505, all trans; IIIa, 0-25°, 48, -4.5°, 1.5507, all trans; IIIa, reflux, 37, -2.5°, 1.5510, all trans. To establish the stability to isomerization under the above exptl. conditions, known cis-1,2-dibromocyclohexane (II) and IIa were refluxed 12 hrs. with Br and AgBr. II, m. 10.0°, n25D 1.5512, was recovered with a 60% yield of material, m. 6.5°, n25D 1.5511, all cis; and IIa, m. -4.5°, n25D 1.5505, similarly yielded 94% material, m. -4.5°, n25D 1.5505, all trans. Although the data did not distinguish partial isomerization from complete retention of configuration a very large proportion of II survived the reaction. No isomerization of II took place on 12 hrs. refluxing with Br and AgBr in anhydrous CCl4. The mechanistic implications were discussed briefly.
