Iron(0)-Catalyzed Transfer Hydrogenative Condensation of Nitroarenes with Alcohols: A Straightforward Approach to Benzoxazoles, Benzothiazoles, and Benzimidazoles

The iron-catalyzed hydrogen transfer strategy has been applied to the redox condensation of o-hydroxynitrobenzene with alcohol, leading to the formation of benzoxazole derivatives. A wide range of 2-substituted benzoxazoles were synthesized in good to excellent yields without the addition of an external redox agent. A series of control experiments provided a plausible mechanism. Furthermore, the reaction system was successfully extended to the synthesis of benzothiazoles and benzimidazoles.

Synthesis, structure, electrochemical properties and superoxide radical scavenging activities of two thiocyanate copper(II) complexes with different pyridyl-benzoxazole ligands

Reaction of 2-(2′-pyridyl)benzoxazole (2-PBO) or 2-(4′-pyridyl)benzoxazole (4-PBO) ligands with CuSCN afforded two thiocyanate copper (II) complexes, Cu(2-PBO) (SCN)(2) (1) and Cu(4-PBO)(2)(SCN)(2) (2), have been characterized by elemental analysis, UV-Vis, IR spectra and single-crystal X-ray diffraction. The structural analysis reveals that although the structures of complexes 1-2 are both four coordinated and show plane quadrilateral structure, the distorted of complex 1 is greater than 2. The cyclic voltammogram of complexes 1-2 represent quasi-reversible Cu2+/Cu+ pairs. The superoxide radical scavenging test in vitro showed that complex 1-2 had significant antioxidant activity on superoxide radicals, and the activity of complex 2 was higher than that of 1. This may be due to the structure of complex 2 being closer to the Cu, Zn-SOD. (C) 2018 Elsevier B.V. All rights reserved.

QSAR Modeling and Drug-Likeness Screening for Antioxidant Activity of Benzofuran Derivatives

In order to explore the relationship between the antioxidant activity and structure of fifteen benzofuran derivatives, we carried out a QSAR study using multiple linear regression (MLR) and artificial neural network (ANN) methods. Six descriptors were used as input data (molar weight, surface area, octanol-water partition coefficient, hydration energy, highest occupied molecular orbital energy and lowest unoccupied molecular orbital energy). The electronic properties were derived at the B3LYP/6-31 G (d,p) level. Benchmarks on furan and benzofuran subunits and their comparison to the experiment showed that this level of theory is good enough. The output data correspond to the antioxidant activity as given by IC50. The predicted properties are in agreement with experimental values. Our study shows that 80% of studied molecules are in accordance with the Lipinski and Veber rules and reach the optimal lipophilicity indices. In addition, statistical analysis reveals that ANN technique with (6-2-1) architecture is more significant than MLR model. (C) 2019 Elsevier B.V. All rights reserved.

Kinetically unstable 2-isocyanophenol isolated in cryogenic matrices: Vibrational excitation, conformational changes and spontaneous tunneling

Monomers of 2-isocyanophenol were generated in low-temperature solid Ar and N2 matrices by UV-irradiation of benzoxazole and characterized by infrared (IR) spectroscopy. Near-IR narrowband excitation of the first OH-stretching overtone of 2-isocyanophenol isolated in an N2 matrix converted the most stable cis into the higher-energy trans conformer. Interconversions between these conformers also occurred when the sample was vibrationally excited by the full, or filtered, broadband light of the IR spectrometer source, notably, with different isomerization rate constants. A spontaneous trans. cis decay, via H-tunneling, was observed for N2 matrix kept in dark. In an Ar matrix, only the cis conformer was observed.

Novel high-performance poly(benzoxazole-co-imide) resins with low dielectric constants and superior thermal stabilities derived from thermal rearrangement of ortho-hydroxy polyimide oligomers

Unsatisfied dielectric property and insufficient thermal stability are major obstacles for the commercialization of polyimide resins in the future ultralarge scale integration (ULSI) or radar-wave-transparent composite applications. The incorporation of ortho-hydroxy diamine into a common phenylethynyl terminated oligoimides, aiming to subsequently form additional rigid benzoxazole units by the thermal rearrangement (TR), were prepared. The effects of TR-able codiamine on the processing ability of oligoimides, molecular packing and properties, including thermal stability, dielectric property and bonding ability to reinforcing fibers, for the resulting poly(imide-co-benzoxazole) (PI-co-PBOs) resins have been examined in detail. These thermally rearranged PI-co-PBO resins exhibit reduced dielectric constants of 2.56-3.4 at f = 0.1 GHz, lower than the cured PI with a dielectric constant of 3.55. Meanwhile, the 5 wt% weight loss temperature (T-d5) of the resultant resins increases from 455 degrees C for the cured PI to 491 degrees C for the PI-co-PBO-60 containing 60 mol% benzoxazole unit, and correspondingly, the tensile modulus of PI-co-PBO-60 reaches 2.47 GPa, which is 76% higher than that of the cured PI. These resultant PI-co-PBOs exhibit the combined excellent properties, indicating them a great potentials as the new low-dielectric constant polymer resins in microelectronic industries or advanced composites.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Excited-state intramolecular proton transfer of 6-amino-2-(2 ‘-hydroxyphenyl) benzoxazole (6A-HBO) in different solvents

The excited-state intramolecular proton transfer (ESIPT) process of 6-amino-2-(2 ‘-hydroxyphenyl) benzoxazole (6A-HBO) was investigated using density functional theory and time-dependent density functional theory methods with B3LYP and TZVP basis sets. n-Heptane, dichloromethane, methanol, and acetonitrile were chosen as a series of polar solvents in calculations using the IEFPCM model. To obtain a more comprehensive ESIPT mechanism, we constructed the S-0 and S-1 states’ potential energy surfaces (PESs) by incrementally twisting the OH bond and increasing the distance of O-H bond. Based on the analysis of the bond lengths, the IR vibrational spectra, and the frontier molecular orbits (MOs), the intramolecular hydrogen bonding (OH…N) is clearly strengthened, and the charge is redistributed in the S-1 state. The results of calculated absorption spectrum are in accord with the experimental data. The fluorescence spectrum of 6A-HBO-enol showed a normal red shift, but the red shift of the 6A-HBO-keto is larger and increases with the solvent polarity, indicating a charge transfer. Analysis of the PESs indicates a lower potential energy barrier in S-1 state for the proton transfer from the O atom to the N atom, with the excited state potential barrier slightly decreasing with the increase of the solvent polarity.
