A reaction route accounting for the formation of levulinic acid from 5hydroxymethylfuran-2-carbaldehyde was deduced on the basis of the mechanism previously offered by Horvat, to match the steps with more details. A newly deduced reaction route was proposed between two intermediate products within this mechanism, and the probabilities of the two mechanisms were compared by Gaussian 03 software....

Benzotiazole and pyrimidine have been reported to act as effective pharmacophores. However, much less work as been carried out on these heterocycles fused with each other. In the present study, we report the synthesis of a series of 8-chloro-3(phenylcarbonoimidoyl)-10a-H-pyrimido [2,1-b][1,3]benzothiazole-2-thiol. This series was synthesized by the reaction of 8-chloro-2-sulfanyl-10a-H-pyrimido...

In this paper, a novel phenyl-thiophene-2-carbaldehyde compound-based flexible substrate material has been presented. Optical and microwave characterization of the proposed material are done to confirm the applicability of the proposed material as a substrate. The results obtained in this work show that the phenyl-thiophene-2-carbaldehyde consists of a dielectric constant of 3.03, loss tangent ...

The dinuclear title compound, [Co(2)Cl(3)(C(6)H(4)NO(2))(C(6)H(6)N(2)O)(2)(C(2)H(5)OH)], contains two six-coordinate Co(II) atoms with different octa-hedral coordination environments. One Co(II) atom is coordinated by two N atoms from one pyridine-2-carbaldehyde oxime ligand, by one terminal and one bridging Cl(-) ion, by one O atom from an ethanol mol-ecule, and by one O atom from a bridging p...

We report the specific collision of a single murine cytomegalovirus (MCMV) on a platinum ultramicroelectrode (UME, radius of 1 μm). Antibody directed against the viral surface protein glycoprotein B functionalized with glucose oxidase (GOx) allowed for specific detection of the virus in solution and a biological sample (urine). The oxidation of ferrocene methanol to ferrocenium methanol was car...

In  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. Covalent  grafting of silica coated magnetite nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs). Then, Schiff base condensation  of AmpSCMNPs with acet...
