We report herein a visible-light-promoted, highly practical carboxylation of readily accessible aryl triflates at ambient temperature and a balloon pressure of CO2 by the combined use of palladium and photoredox Ir(III) catalysts. Strikingly, the stoichiometric metallic reductant is replaced by a nonmetallic amine reductant providing an environmentally benign carboxylation process. In addition, one-pot synthesis of a carboxylic acid directly from phenol and modification of estrone and concise synthesis of pharmaceutical drugs adapalene and bexarotene have been accomplished via late-stage carboxylation reaction. Furthermore, a parallel decarboxylation-carboxylation reaction has been demonstrated in an H-type closed vessel that is an interesting concept for the strategic sector. Spectroscopic and spectroelectrochemical studies indicated electron transfer from the Ir(III)/DIPEA combination to generate aryl carboxylate and Pd(0) for catalytic turnover.

Combined water pollution with the coexistence of heavy metals and organic contaminants is of great concern for practical wastewater treatment. In this study, a jaboticaba-like nanocomposite, titanate nanotubes supported TiO2 (TiO2/TiNTs), was synthesized by a two-step hydrothermal treatment. TiO2 /TiNTs had large surface area, abundant of -ONa/H groups and fine crystal anatase phase, thus exhibited both good adsorptive performance for Cu(II) and high photocatalytic activity for phenanthrene degradation. The maximum Cu(II) adsorption capacity on TiO2/TiNTs was 115.0 mg/g at pH 5 according to Langmuir isotherm model, and > 95% of phenanthrene was degraded within 4 h under UV light. TiO2/TiNTs showed about 10 times higher observed rate constant (k(obs) ) for phenanthrene degradation compared to the unmodified TiNTs. More importantly, the coexistence of Cu(II) promoted photocatalytic degradation of phenanthrene, because the incorporated Cu(II) in the lattice of TiNTs could trap photo-excited electron and thus inhibited the electron-hole recombination. Density functional theory (DFT) calculation indicated that the sites of phenanthrene with high Fukui index (f(0)) preferred to be attacked by center dot OH radicals. The quantitative structure-activity relationship (QSAR) analysis revealed that the degradation intermediates had lower acute toxicity and mutagenicity than phenanthrene. TiO2/TiNTs also owned high stability, as only slight loss of Cu(II) and phenanthrene removal efficiency was observed even after four reuse cycles. The developed material in this study is of great application potential for water or wastewater treatment with multi-contaminants, and this work can help us to better understand the mechanisms on reaction between Ti-based nanomaterials and different kinds of contaminants.

By using the reduced Schiff base tricarboxylate ligand H(3)cip, one novel 3D Cd-based coordination polymer (Cd-CP) with the formula [Cd(Hcip)(bpea)(0.5)(H2O)](n) (H(3)cip = 5-(3-carboxybenzylamino)isophthalic acid, bpea = 1,2-bis(4-pyridyl)ethane) has been solvothermally synthesized. The prepared Cd-CP possesses a 4-connected CdSO4 net based on dinuclear {Cd-2} units. Luminescence measurements revealed that the complex exhibited ratiometric turn-on luminescence responses toward Al3+ and Cr3+ with a significant color change, which could be easily distinguished by the naked eye under ultraviolet light. Cd-CP can also respond to Fe3+ through a turn-off mechanism. Interestingly, the luminescence quenched by Fe3+@Cd-CP can be recovered and increased significantly by adding some competitive Al3+, while Cr3+ can only marginally increase the luminescence intensity of Fe3+@Cd-CP. Moreover, the detection of the three aforementioned metal ions can be realized by using Cd-CP-coated test papers, extending the potential application regions of the reported material to point-of-care tests and environmental field studies.

An article FACILE PREPARATION OF 3,4-BENZOCOUMARINS FROM 2-ARYLBENZOIC ACIDS WITH NCS AND NaI WOS:000573109600003 published article about O BOND FORMATION; CARBOXYLIC-ACIDS; BENZOCOUMARINS; LACTONIZATION; CYCLIZATION; ACCESS; NIS in [Nakamura, Momoko; Togo, Hideo] Chiba Univ, Grad Sch Sci, Inage Ku, Yayoi Cho 1-33, Chiba 2638522, Japan in 2020.0, Cited 31.0.

Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.

The condensation of MeP(SiMe3)(2) with a series of 5-substituted isophthaloyl chlorides (5-R’C6H3-2,6-{C(O)Cl}(2)) affords the diphosphametacyclophanes m-{-C(O)-C6H3-5-R’-(C(O)PMe)}(2) (R’ = I, Me, tBu, Ph, and p-NCC6H4); the analogues m-{-C(O)-C5H3N-(C(O)PMe)}(2) and m-{-C(O)-C6H4-(C(O)PPh)}(2) are similarly obtained in preference to higher oligomers, in contrast to precedent reports. The cyclophanes all adopt butterfly-like conformations in the solid state with the P-organyl substituents adopting mutually exo arrangements. Structural and computational data suggest the nature of the 5-R substituent is key in directing the inter-ring angle and the extent of LUMO stabilization about the diketophophanyl scaffold. The latter is substantiated by UV/vis spectroscopy and cyclic voltammetry, which demonstrate these cyclophanes to be appreciably comparable to the diketophosphanyl systems commonly explored in the context of organic electronic materials; intriguingly, the distinct dikeophosphanyl moieties within the macrocycles appear effectively insulated by the macrocycle geometry, rather than acting as a through-conjugate.

The complete conversion of hemicellulose, cellulose and lignin in lignocellulosic biomass into value-added chemicals is of great significance in biorefinery processes. Herein, a cascade-step strategy was developed for the conversion of hemicellulose and lignin into mixed organic acids, and cellulose into ethylene glycol. Typical biomass of Miscanthus was first treated with formic acid in the presence of H2O2, giving a formic acid solution and cellulosic biomass. Lignin in Miscanthus was oxidized to low polymerized organic acids through linkage cleavages and aromatic ring ruptures during the treatment process, forming a homogeneous formic acid solution with a weight yield of 95%. Hemicellulose was transformed into maleic acid at 56.2% selectivity via a hydrolysis-dehydration-oxidation process. Both hemicellulose and lignin were degraded into organic acids with an overall weight yield of 92.4%. The cellulose in the solid residue had a hydrophilic surface and is highly accessible to catalysts in the aqueous solution, and it was totally converted into ethylene glycol with a yield of up to 65.7% over a binary catalyst of H2WO4-Ru/C. Relying on such a cascade reaction strategy, the three major components of Miscanthus were transformed into mixed organic acids and ethylene glycol, which provides a potential strategy for complete valorisation of biomass into value-added chemicals.

Porous microspheres from discotic tripeptides have been investigated as potential candidates for drug delivery vehicles. The C-3 symmetric discotic tripeptide adopts a supramolecular helical column structure by three fold intermolecular hydrogen bonding interactions as well as face to face pi-pi stacking interactions. But the C-2 symmetric discotic tripeptide adopts a supramolecular dimer like structure by six-fold intermolecular hydrogen bonding interactions and face to face pi-pi stacking interactions. Field emission scanning electron microscopy (FE-SEM) revealed that the C-3 symmetric discotic tripeptide exhibits bird nest-like porous microsphere morphology formed by the assembly of the individual columns. However the C-2 symmetric discotic tripeptide forms round clay pitcher like porous microspheres. These porous microspheres have been used as potential carriers for the sustained release of a bacteriostatic antibiotic sulfamethoxazole. The spectroscopic studies as well as the growth inhibition of E. coli reveal that the round clay pitcher-like porous microspheres are more efficient than the bird nest-like porous microspheres for the sustained release of drugs. The report highlights the importance of the self-assembly pattern for the fabrication of advanced functional materials.

We found that in situ generated cerium(IV) carboxylate generated by mixing the precursor Ce((OBu)-Bu-t)(4) with the corresponding carboxylic acids served as efficient photocatalysts for the direct formation of carboxyl radicals from carboxylic acids under blue light-emitting diodes (blue LEDs) irradiation and air, resulting in catalytic decarboxylative oxygenation of aliphatic carboxylic acids to give C-O bond-forming products such as aldehydes and ketones. Control experiments revealed that hexanuclear Ce(IV) carboxylate clusters initially formed in the reaction mixture and the ligand-to-metal charge transfer nature of the Ce(IV) carboxylate clusters was responsible for the high catalytic performance to transform the carboxylate ligands to the carboxyl radical. In addition, the Ce(IV) carboxylate cluster catalyzed direct lactonization of 2-isopropylbenzoic acid to produce the corresponding peroxy lactone and gamma-lactone via intramolecular 1,5-hydrogen atom transfer (1,5-HAT).

A mild and efficient protocol for the intramolecular aromatic C-H oxygenation of 2-biphenylcarboxylic acids has been achieved via iron photocatalysis. The 2-biphenylcarboxylic acids with a diverse array of substituents at both phenyl rings could furnish the oxygenation products in good to excellent yields. We speculate that the aryl carboxylate-iron(III) complexes should generate the aroyloxy radicals and iron(II) upon visible light irradiation.
