Palladium Catalyzed Electrophilic C2-Arylation of Azoles by Aryltriazenes in Ionic Liquid Promoted by Acidic Ionic Liquid

A green C-H bond activation of azole based bio-pertinent substrates such as benzoxazole, benzothiazole, benzimidazole are accomplished using readily prepared 1-aryltriazenes as arylating agent. Under an optimized condition employing Pd(OAc)(2)and CuI in either hydrophilic [Bmim][BF4] or hydrophobic [Bmim][PF6] IL medium with [BMIM(SO3H)][OTf] as a promoter, these arylation reactions proceeded smoothly to afford 2-aryl substituted azoles in acceptable to better yields besides noticeable functional group tolerance. The prospective for recovery and re-use of ionic liquid solvent is demonstrated.

Phosphorescent Cyclometalated Iridium(III) Complexes Bearing Ethynyl-Extended 2-(2′-Hydroxyphenyl) Benzoxazole Ancillary Ligands

This article describes the synthesis and full photophysical studies at room and low temperature of a series of iridium(III) complexes incorporating an ethynyl-extended benzoxazole-based ancillary ligand. The electronic nature of the terminal end-group of the ancillary ligand was modulated by the simple introduction of electron-donating (Me, NBu2) or -withdrawing (CN) groups. For all complexes, TD-DFT calculations showed that the lowest-lying transition was ligand-centered and that the nature of the first triplet state was very sensitive to electronic parameters leading to a charge transfer (CT) or locally excited (LE) excited state, always centered on the ancillary ligand. Singlet oxygen sensitization studies were performed on all compounds, showing that iridium(III) complexes containing cyano-functionalized ligands feature sensitization parameters, making them attractive candidates for photodynamic therapy.

Consecutive Oxidation/Condensation/Cyclization/Aromatization Sequences Catalyzed by Nanostructured Iron(III)-Porphyrin Complex towards Benzoxazole Derivatives

A facile, efficient, and eco-friendly strategy to access benzoxazole heterocyclic products has been accomplished through oxidation of catechols followed by condensation/cyclization/aromatization sequences. This process is catalyzed by nanostructured iron(III)-porphyrin complex to form desired benzoxazole derivatives at room temperature under air condition. The procedure is widely applicable to diverse amines, and can provide the heterocyclic products in a scalable fashion, as well. One of the most significant types of oxidizing agents in nature is the iron-porphyrin complexes (0.1 mol-%), existing in the structure of hemoglobin. They have benefits such as low toxicity and high oxidation potential for many substrates.

Gas transport properties of mixed matrix membranes based on thermally rearranged poly(hydroxyimide)s filled with inorganic porous particles

In this study, we explore the use of two kinds of inorganic sieves, microporous MFI zeolite and mesoporous MCM-41 silica, as fillers to enhance the gas transport characteristics of thermally rearranged (TR) poly(hydroxyimides) (HPI). To the best of our knowledge, this is the first report on the use of these fillers to modify properties of TR HPIs, except for our previous research on MCM-41 filled HPIs based on BPADA dianhydride. In this work, 6FDA-HAB and BPADA-HAB varying in gas permeability and properties were selected as matrices for preparation of mixed matrix membranes (MMM) with the aim of studying the effect of both the kind of filler and a matrix on thermal rearrangement and properties of the resultant TR-MMMs. In addition to pure gas permeability measurements, HPIs and MMMs were examined by WAXD, SEM, TGA, DMA, and tensile tests before and after thermal rearrangement. For all MMM precursors, the permeability increased in proportion to the filler loading (e.g. by 1.2-4.4 times for O-2) while selectivity remained virtually the same. The same effect of improved permeability and maintained selectivity was observed for the series of TR-MMMs; for example, TR-MMM based on 6FDA and filled with 7 wt% of MCM-41 exhibited 6.7 fold higher O-2 permeability over its filled precursor. The permeation properties of the filled membranes showed a strong dependence on both the kind of matrix and filler. The addition of MCM-41 particles to BPADA-HAB increased permeability more than the incorporation of the similar amount of MFI ones, while the contrary was true for 6FDA-HAB. The best result, comprising the position on the upper bound for He/N-2, has been achieved for 6FDA-HAB filled with 25 wt% of MFI, whereas its TR analogue showed the highest 20.4 fold permeability improvement.

Post-synthetic modification of CARDO-based materials: application in sour natural gas separation

A new homopolymer, 6FDA-CARDO(t-Bu), was prepared from 6FDA-CARDO through one-step chemical modification by adding bulky tert-butyl groups, using Friedel-Crafts alkylation. The incorporation of the bulky groups led to a significant increase in the fractional free volume (FFV) within the matrix of membranes prepared from the modified polymer. The thermal properties of the modified polymer were not greatly affected compared to those of its parent 6FDA-CARDO homopolymer, where the T-d5% and the T-g were measured to be 517 degrees C and 366 degrees C, respectively. The hydrazine-assisted cleavage of 6FDA-CARDO(t-Bu) led to the preparation of the new diamine monomer CARDO(t-Bu) in high yield. Pure-gas and multicomponent sweet and sour mixed-gas permeation studies of dense films prepared from 6FDA-CARDO(t-Bu) were carried out and compared to those of membranes prepared from 6FDA-CARDO. For example, the carbon dioxide (CO2) pure-gas permeability of the 6FDA-CARDO(t-Bu) membrane was measured at 100 psi feed pressure and 22 degrees C, and found to be 271 Barrer which is 4.6-fold higher when compared to that of 6FDA-CARDO membranes. Due to a simultaneous increase in the methane (CH4) pure-gas permeability, a reduction in the CO2/CH4 selectivity of the 6FDA-CARDO(t-Bu) membrane was recorded. A similar effect was observed for the sweet mixed-gas separation studies. Interestingly, the sour mixed-gas (containing 21% hydrogen sulfide, H2S) separation properties of the 6FDA-CARDO(t-Bu) membrane showed a different trend. At 500 psi and 22 degrees C, the H2S/CH4 selectivity was 10% higher, and the CO2 and H2S permeability coefficients were 3.2- and 3.8-fold, respectively, higher compared to those obtained for 6FDA-CARDO membranes.

Halo-Bridged Abnormal NHC Palladium(II) Dimer for Catalytic Dehydrogenative Cross-Coupling Reactions of Heteroarenes

This work describes the dehydrogenative coupling of heteroarenes using a dimeric halo-bridged palladium(II) catalyst bearing an abnormal NHC (aNHC) backbone. The catalyst can successfully activate the C-H bond of a wide range of heteroarenes, which include benzothiazole, benzoxazole, thiophene, furan, and N-methylbenzimidazole. Further, it exhibited good activity for heteroarenes bearing various functional groups such as CN, CHO, Me, OMe, OAc, and Cl. Additionally, we isolated the active catalyst by performing stoichiometric reaction and characterized it as the acetato-bridged dimer of (aNHC)PdOAc by single-crystal X-ray study.
