The present paper introduces a study on the preparation and characterization of cellulose acetate – TiO2 nanotubes membrane. In order to be used as a hemodialysis membrane, fraxiparinized nanotubes have been incorporated into the cellulose matrix. Fraxiparine embedding was performed via strong ...
In the heterobimetallic compound PbTi4(OAllyl)9.9(OiPr)6.1(OAc)2, obtained from Ti(OiPr)4 and Pb(OAc)2 in the presence of allylic alcohol, two [Ti2(OR)8(OAc)]− units are coordinated to the central lead ion exclusively through bridging OR groups. The lone pair of the lead ion (E) occupies an equa...
A Wittig-Still type [2,3]-sigmatropic rearrangement of (trimethylsilyl)methyl allyl ethers has been developed.
The bioactive alkaloid natural product perophoramidine and the related family of compounds known as the communesins have inspired the synthesis community for more than a decade. Many of the elegant approaches have required the synthesis of complex intermediates that have not always reacted in th...
Microwave spectra of iodomethyl methyl ether and its 10 isotopic species have been measured. A least-squares analysis of the observed frequencies gave rotational and quartic centrifugal distortion constants and all the components of the nuclear quadrupole coupling constant tensor. The rs structu...
Microwave spectra of iodomethyl methyl ether (CH3OCH2I) and its two deuterated species have been measured. A least-squares analysis for the observed frequencies gave rotational, centrifugal distortion constants and all the components of the nuclear electric quadrupole coupling constant tensor of...
4-(Bromomethyl) coumarins 1 have been reacted with vanillins, 2 and 2A to obtain the corresponding ethers 3 and 5. Ethers 3 have been reacted with ethyl cyanoacetate to obtain the unsaturated esters 4. Ethers 5 have been converted to the corresponding 4-(2′-benzo[b] furanyl) coumarins 6 by an i...
Side-bridged cyclam transition metal complexes (M = Ni(II), Cu(II) and Zn(II)) bearing a phenolic ether or phenolate pendent arm have been synthesised. For [NiL1]+ and [CuL1]+, evidence for a phenoxyl radical was obtained (quasi reversible peak at +0.74 V and +0.48 V respectively), as well as ox...
A series of highly alkaline durable crosslinked anion exchange membranes (AEMs) is prepared via elimination reaction using a sodium salt of 4,4′(5′)-di(hydroxybenzo)-18-crown-6 as the crosslinker, and quaternary ammonium (QA) as the cation group. The ionic conductivity, ionic exchange capacity...
With the aid of a series of model thioether or thioglycoside containing polyols protected with combinations of benzyl ethers and 2-naphthylmethyl ethers it is demonstrated that the latter are readily cleaved selectively under hydrogenolytic conditions in the presence of the frequently catalyst-p...
High-performance anion exchange membranes (AEMs) are in need for practical application of AEM fuel cells. Novel branched poly(ether ether ketone) (BPEEK) based AEMs were prepared by the copolymerization of phloroglucinol, methylhydroquinone and 4,4′-difluorobenzophenone and following functional...
Fluorinated iodoacetate (CF3)2CFCH2CHICH2OAc (1) (prepared by radical addition of perfluoroisopropyl iodide to allyl acetate) and fluorinated iodohydrin (CF3)2CFCH2CHICH2OH (2) (prepared from 1) were converted to the corresponding perfluoroalkylated oxirane (CF3)2CFCH2CH(O)CH2 (3) in the yie...
1-Methylcyclopropene (1-MCP) is a cyclopropene compound that is widely used as an ethylene antagonist to extend the storage life of fresh fruit but has a difficulty in its use due to its chemically unstable and physically volatile properties. A cyclopropene compound with a long chain substituent...
As a continuation to our research, a series of novel Bcr-Abl inhibitors incorporated with 6-phenyl-1H-indazol-3-amine as hinge binding moiety (HBM) were developed based on confirmation analysis. Biological results indicated that these compounds exhibited an enhanced inhibition against Bcr-AblWT ...
Herein, Cu was incorporated into ZnO lattice to reduce its band gap as well as to extend its visible radiation response. The obtained Cu-ZnO was continuously integrated with g-C3N4 to create Cu-ZnO/g-C3N4 Z-direct scheme photocatalyst for advanced atrazine removal. Radical scavenging experiments...
The kernel of photocatalytic technology is to exploit photocatalytic materials with high efficiency, stability and easy recovery. Herein, we designedly prepare a magnetic quantum dot (Fe3O4 QDs) as co-catalyst to modify Z-scheme Bi2O4/g-C3N4 (Bi/CN) composite photocatalyst via combining calcinat...
In this study, a series of α-Fe2O3/g-C3N4(FCN) photocatalysts for CO2 reduction at 0.6 MPa to produce CH3OH is synthesized via hydrothermal method and the FCN hybrid shows greater absorption of visible light than pure g-C3N4 due to the introduction of α-Fe2O3 (narrow bandgap). The Z-scheme het...
The Horner–Wadsworth–Emmons reactions of 2-fluoro-2-diethylphosphonoacetic acid with 2-{[(triisopropylsilyl)oxy]methyl}cyclopentanone (2-TOM-cyclopentanone) using methylmagnesium chloride furnished the corresponding tetra-substituted fluoroolefin in a Z-selective manner (E/Z = 9:91). A facile ...
Novel WO3/g-C3N4/Ni(OH)x hybrids have been successfully synthesized by a two-step strategy of high temperature calcination and in situ photodeposition. Their photocatalytic performance was investigated using TEOA as a hole scavenger under visible light irradiation. The loading of WO3 and Ni(OH)x...
The construction of Z-scheme system to achieve efficient photolysis of water to produce hydrogen is a promising approach in the field of photocatalysis. In this work, two dimensionally (2D) crystallized Ni(OH)2 nanosheets are loaded upon the surfaces of three dimensionally macroporous g-C3N4 (3D...
