A novel aromatic diamine monomer, 4-(4-diethylamino)phenyl-2,6-bis(4-(4-aminophenoxy)phenyl)pyridine (EPAPP), containing pyridine ring units, ether linkage moieties and diethylaminophenyl pendent groups, has been designed and synthesized through three-step methods, and then used to prepare for a series of polyimides with commercial aromatic dianhydrides via two-step solution polycondensation. The resulting polyimides showed good solubility in common polar solvents, such as NMP, DMF, DMSO. They exhibited high thermal stability with the glass transition temperature (T(g)s) more than 254 degrees C, and the temperature of 10% weight loss over 544 degrees C with more than 64% residue at 800 degrees C under nitrogen. They presented excellent hydrophobic properties with the contact angle in the range of 81.9-91.9 degrees. In addition, the results of Wide-angle X-ray Diffraction (WAXD) indicated that these polymers revealed an amorphous structure.

A fast and facile synthesis of TiO2- Al2O3 nanocomposite based on Microwave (MW) irradiation is presented. The nanocomposite development were corroborated by X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), energy-dispersive X-ray (EDX),and Fourier transform infrared spectroscopy (FT-IR)analysis. The XPS analyzed results affirmed that elements on the nanocomposite surface were Al and O. Electrochemical properties of the as prepared TiO2-Al2O3 nanocomposites were studied thoroughly to determine the sensing activity of the nanocomposites towards 3,4-Diaminotoluene (3,4-DAT) which is a harmful or hazardous chemical using I-V method. Selective electrochemical sensor using TiO2-Al2O3 nanocomposite onto glassy carbon electrode (GCE) was assembled and the details electrochemical investigation of 3,4-Diaminotoluene (3,4-DAT) was developed. It was calibrated using in range of 3,4-DAT concentration and data were plotted as current versus concentration. Considering the highest linearity (r(2)=0.99)of calibrated range, the linear dynamic range (1.0 pM similar to 1.0 mu M) was found. Employing the slope of calibration curve, the sensitivity (0.5024×10(3) mu A mu M(-1)cm(-3)) and detection limit (0.19 +/- 0.01 pM) were estimated. Besides this, the selective 3,4-DAT chemical sensor was shown long-term stability and precious reproducibility with very short response time without any interference effect.

We report on the tetraethylphosphorodiamidate (-OP(O)(NEt2)(2)) group as an effective directed metalation group (DMG). Lithiation-electrophile quench of 1 provides a general synthesis of ortho-substituted aryl and naphthyl phosphorodiamidates 4-8. We also describe the phospha anionic ortho-Fries (AoF) rearrangement of the phosphorodiamidates 1a,1b -> 2 or 3 and its vinylogous counterpart to the ortho-tolyl phosphorodiamidates 5b -> 13. Intermolecular competition experiments demonstrate the approximately equal DMG strength of the -OP(O)(NEt2)(2) and the most powerful OCONEt2 groups.

Herein, we first present a nickel-catalyzed arylation and alkenylation of tert-cyclobutanols with aryl/alkenyl triflates via a C-C bond cleavage. An array of.-substituted ketones was obtained in moderate-to-good yields, thus featuring earth-abundant nickel catalysis, broad substrate scope, and simple reaction conditions. Preliminary mechanistic experiments indicated that beta-carbon elimination pathways might be involved in the catalytic cycle.

In the present work, the accelerated ageing process of sherry vinegar has been studied at pilot scale by means of the joint application of ultrasound, micro-oxygenation and wood chips (American oak, French oak and Spanish oak). The CIELab parameters have been studied as well as the polyphenolic and volatile content of the aged vinegar samples. Vinegars aged with American oak presented different chromatic characteristics to those aged with French and Spanish oak and a lower polyphenolic and volatile content than the latter ones. On the other hand, Spanish oak generated vinegars with a higher content of volatile compounds and an intermediate poly phenolic profile between those obtained using French and American oak. In addition, the use of ultrasound for a period between 4 and 21 days, generated vinegars with similar characteristics to others that were aged in the traditional way for between 2 and 6 months. It has been demonstrated that the use of ultrasound, combined with micro-oxygenation and chip addition, is a technique which can accelerate the ageing process of vinegars at a pilot scale, so it could be a viable alternative to obtain sherry vinegars aged in a shorter time.

Twenty clusters of the general formula [(mu-H)(2)Ru-3(mu(3)-S)(CO)(7)(mu-P-P*)] (P-P* = chiral diphosphine of the ferrocene-based Walphos or Josiphos families) have been synthesised and characterised. The clusters have been tested as catalysts for asymmetric hydrogenation of tiglic acid [trans-2-methyl-2-butenoic acid]. The observed enantioselectivities and conversion rates strongly support catalysis by intact Ru-3 clusters. A catalytic mechanism involving an active Ru-3 catalyst generated by CO loss from [(mu-H)(2)Ru-3(mu(3)-S) (CO)(7)(mu-P-P*)] has been investigated by DFT calculations.

The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd-2(dba)(3)/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(eta(3)-C3H5)Cl](2)/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the eta(3)-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.

In search of new active molecules against MCF-7, A549 and HepG2, tetrazole based pyrazoline and isoxazoline derivatives under both conventional and ultrasonic irradiation method were designed and efficiently synthesized. Structures of newly synthesized compounds 5a-h and 6a-h were characterized by H-1 NMR, C-13 NMR, MS and elemental analysis. Several derivatives were found to be excellent cytotoxic against MCF-7, A549 and HepG2 cell lines characterized by lower IC50 values (0.78-3.12 mu g/mL). Compounds 5b and 5c demonstrated an antiproliferative effect comparable to that of CA-4. Western blot analysis revealed that, reported compounds accumulate more tubulin in the soluble fraction. Docking studies suggested that, binding of these compounds mimics at the colchicine site of tubulin. In vitro study revealed that the tetrazole based pyrazolines and isoxazolines may possess ideal structural requirements for further development of novel therapeutic agents.

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one-pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23-90 degrees C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with a wide variety of useful functional groups and were successfully applied as chiral ligands for metal catalysis. Computational studies gave a first rationalization of the low activation energy for the cycloaddition based on counter-intuitive favorable dispersive interactions in the transition state.
