To study the relationship between rate and driving force of intramolecular dissociative electron transfers, a series of donor-spacer-acceptor (D-Sp-A) systems has been devised and synthesized. cis-1,4-Cyclohexanedyil and a perester functional group were kept constant as the spacer and acceptor, respectively. By changing the aryl substituents of the phthalimide moiety, which served as the donor, the driving force could be varied by 0.74 eV. X-ray diffraction crystallography and ab initio conformational calculations pointed to D-Sp-A molecules having the cis-(cyclohexane) equatorial(phthalimido)axial(perester) conformation and the same D/A orientation. The intramolecular dissociative electron-transfer process was studied by electrochemical means in N,N-dimethylformamide, in comparison with thermodynamic and kinetic information obtained with models of the acceptor and the donor. The intramolecular process consists of the electron transfer from the electrochemically generated phthalimide-moiety radical anion to the peroxide functional group. The electrochemical analysis provided clear evidence of a concerted dissociative electron-transfer mechanism, leading to the cleavage of the O-O bond. Support for this mechanism was obtained by ab initio MO calculations, which provided information about the LUMO of the acceptor and the SOMO of the donor. The intramolecular rate constants were determined and compared with the corresponding intermolecular values, the latter data being obtained by using the model molecules. As long as the effective location of the centroid of the donor SOMO does not vary significantly by changing the aryl substituent(s), the intramolecular dissociative electron transfer obeys the same main rules already highlighted for the corresponding intermolecular process. On the other hand, introduction of a nitro group drags the SOMO away from the acceptor, and consequently, the intramolecular rate drops by as much as 1.6 orders of magnitude from the expected value. Therefore, a larger solvent reorganization than for intermolecular electron transfers and the effective D/A distance and thus electronic coupling must be taken into account for quantitative predictions of intramolecular rates.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C9H8O. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

Rhodococcus sp. strain JVH1 was previously reported to use a number of compounds with aliphatic sulfide bridges as sulfur sources for growth. We have shown that although JVH1 does not use the three-ring thiophenic sulfur compound dibenzothiophene, this strain can use the two-ring compound benzothiophene as its sole sulfur source, resulting in growth of the culture and loss of benzothiophene. Addition of inorganic sulfate to the medium reduced the conversion of benzothiophene, indicating that benzothiophene metabolism is repressed by sulfate and that benzothiophene is therefore used specifically as a sulfur source. JVH1 also used all six isomers of methylbenzothiophene and two dimethylbenzothiophene isomers as sulfur sources for growth. Metabolites identified from benzothiophene and some methylbenzothiophenes were consistent with published pathways for benzothiophene biodesulfurization. Products retaining the sulfur atom were sulfones and sultines, the sultines being formed from phenolic sulfinates under acidic extraction conditions. With 2-methylbenzothiophene, the final desulfurized product was 2-methylbenzofuran, formed by dehydration of 3-(o-hydroxyphenyl) propanone under acidic extraction conditions and indicating an oxygenative desulfination reaction. With 3-methylbenzothiophene, the final desulfurized product was 2-isopropenylphenol, indicating a hydrolytic desulfination reaction. JVH1 is the first microorganism reported to use all six isomers of methylbenzothiophene, as well as some dimethylbenzothiophene isomers, as sole sulfur sources. JVH1 therefore possesses broader sulfur extraction abilities than previously reported, including not only sulfidic compounds but also some thiophenic species.

Carborane-containing imide compound (Carb-PEPA) was synthesized and added into fluorinated phenylethynyl terminated imide oligomer (AFR-PEPA). The thermal degradation of Carb-PEPA was studied by thermogravimetric analyzer coupled with Fourier transform infrared analysis (TG-FTIR), in situ FTIR and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS). The results show that the Carb-PEPA possesses high char yield in both air and nitrogen due to the formation of B-O bonds in thermal degradation process as identified by TG-FTIR and in situ FTIR. A thermal degradation mechanism for the Carb-PEPA was proposed. The Carb-PEPA crosslinks to form polyimide in the early heating process. Then the degradation of Carb-PEPA happens at higher temperatures, while further degradation could be effectively prevented due to the formation of a protection layer of boron oxide compound. The thermal stabilities of AFR-PEPA and AFR-PEPA containing 15 wt% Carb-PEPA (AFR-PEPA-Carb-15) were also studied by TGA and TG-FTIR. It was observed that AFR-PEPA’s residual weight ratios at 800 C in air and nitrogen increased by 20% and 13.3% respectively with the addition of 15 wt% Carb-PEPA.

De v. 2007, 11, 289-292). Some of our observations regarding citalopram resolution and C-alkylation of a benzofuran analogue (2) to produce didesmethylcitalopram (3) were disputed by Dr. Dancer of H.

Starting from the initial bis-anilinopyrimidine 1, good potency against EphB4 was retained when benzodioxole at C-4 was replaced by an indazole. The key interactions of the indazole with the protein were characterised by crystallographic studies. Further optimisation led to compound 20, a potent inhibitor of the EphB4 and Src kinases with good pharmacokinetics in various preclinical species and high fraction unbound in plasma. Compound 20 may be used as a tool for evaluating the potential of EphB4 kinase inhibitors in vivo.

The synthesis of aromatic ketones containing benzene ring, naphthalene ring or aromatic heterocycle in the presence of zeolite catalysts has been discussed. The replacement of the classical acid catalysts mainly AlCl3 or HF by a zeolite diminishes the environmental problems. Different acylating agents are used acid chlorides, anhydrides or carboxylic acids. The mechanism of the acylation in the presence of zeolite catalysts is supposed to include acylium cation as electrophilic species. BEA zeolite is most studied.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Safety of Thymolphthalein, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 125-20-2, in my other articles.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Safety of Thymolphthalein, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 125-20-2, Name is Thymolphthalein, molecular formula is C28H30O4

Objective Fresh-frozen bone allograft (FFBA) is an alternative to autogenous bone (AB) for reconstructing maxillary bone. Despite the promising clinical results, cell responses to FFBA and AB were not evaluated. Thus, our aim was to compare cells harvested from maxillary reconstructed sites with either AB or FFBA in terms of osteoblast differentiation and to evaluate the effect of culturing cells in contact with FFBA. Methods Cells harvested from three patients submitted to bilateral maxillary reconstruction with AB and FFBA were cultured to evaluate: proliferation, alkaline phosphatase activity, extracellular matrix mineralization and gene expression of osteoblastic markers. The effect of FFBA on osteoblast differentiation was studied by culturing cells harvested from AB in contact with FFBA and evaluating the same parameters. Data were compared using either two-way ANOVA followed by Tukey-b test or Student’s t test (p ? 0.05). Results Cell proliferation was higher in cultures from AB grafted sites and extracellular matrix mineralization was higher in cultures derived from FFBA grafted sites. The gene expression of alkaline phosphatase, RUNX2, bone sialoprotein and osteocalcin was higher in cells derived from FFBA compared with cells from AB grafted sites. However, the exposure of cells derived from AB to FFBA particles did not have any remarkable effect on osteoblast differentiation. Conclusions These results indicate the higher osteogenic activity of cells derived from FFBA compared with AB reconstructed sites, offering an explanation at cellular level of why FFBA could be a suitable alternative to AB for reconstructing maxillary bone defects.
