A range of 1,3,4-oxadiazoles have been synthesized using a UV-B activated flow approach starting from carboxylic acids and 5-substituted tetrazoles. The application of UV light represents an attractive alternative to the traditional thermolytic approach and has demonstrated comparable efficiency and versatility, with a diverse substrate scope, including the incorporation of highly substituted amino acids.

A method for the annulation of amines and carboxylic acids to form pharmaceutically relevant azaheterocycles via organophosphorus P-III/P-V redox catalysis is reported. The method employs a phosphetane catalyst together with a mild bromenium oxidant and terminal hydrosilane reductant to drive successive C-N and C-C bond-forming dehydration events via the serial action of a catalytic bromophosphonium intermediate. These results demonstrate the capacity of P-III/P-V redox catalysis to enable iterative redox-neutral transformations in complement to the common reductive driving force of the P-III/P-V couple.

It remains challenging to achieve the selective cleavage of C-C bonds in lignin or lignin model compounds to produce aromatic products in high yield and selectivity. We have developed a redox-neutral photocatalytic strategy to accomplish this goal in both beta-O-4 and beta-1 lignin models at room temperature (RT) via proton-coupled electron transfer (PCET) process without any pretreatments of substrate, by adjusting the alkalinity of base to obtain a lignin models/base PCET pair with a bond dissociation free energy close to 102 kcal/mol. Without breaking down C-beta-C-gamma bond and any C-O bonds, this PCET method is 100% atom economy and produces exclusive C-alpha-C-beta bond cleavage products, such as benzaldehydes (up to 97%) and phenyl ethers (up to 96%), in high to excellent yields and selectivities. Preliminary studies indicated that the PCET strategy is also effective for the depolymerization of native lignin at RT, thus providing significantly important foundation to the depolymerization of lignin.

We report a new application of N-amino-7-azaindole as a new bidentate-directing group for [Ru(p-cymene)Cl-2](2)-catalyzed C(sp(2))-H alkenylation/annulation of N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamides with internal alkynes to afford N-isoquinolono-7-azaindole via the formation of C-C and C-N bonds. The reaction shows a wide range of substrate scope with different symmetrical and unsymmetrical alkynes, affording the desired product in good to excellent yields. In the case of unsymmetrical alkynes, a highly regioselective product was obtained, which was confirmed by single-crystal X-ray crystallography. A new ruthenium-4-methyl-N-(1H-pyrrolo[2,3-b]pyridin-1-yl)benzamide complex was isolated, and its structure was confirmed by single-crystal X-ray crystallography.

Surface-confined synthesis is a promising approach to build complex molecular nanostructures including macrocycles. However, despite the recent advances in on-surface macro- cyclization under ultrahigh vacuum, selective synthesis of monodisperse and multicomponent macrocycles remains a challenge. Here, we report on an on-surface formation of [6 + 6] Schiff-base macrocycles via dynamic covalent chemistry. The macrocycles form two-dimensional crystalline domains on the micrometer scale, enabled by dynamic conversion of open-chain oligomers into well-defined similar to 3.0 nm hexagonal macrocycles. We further show that by tailoring the length of the alkyl substituents, it is possible to control which of three possible products-oligomers, macrocycles, or polymers-will form at the surface. In situ scanning tunneling microscopy imaging combined with density functional theory calculations and molecular dynamics simulations unravel the synergistic effect of surface confinement and solvent in leading to preferential on-surface macrocyclization.

The separation of desired monomers from a liquid-phase mixture of lignin depolymerization products is necessary to facilitate their upscaling and upgrading for industrial applications. One effective method to separate multiple liquid-phase products is countercurrent chromatography (CCC), which is a common liquid chromatography technique that separates target solutes based on differences in their partitioning in a biphasic solvent system. Effective CCC separation requires the selection of solvent compositions to tune solute partition coefficients. To alleviate the experimental burden of selecting optimal solvent systems, we apply the conductor-like screening model for real solvents (COSMO-RS) method to compute partition coefficients of representative lignin monomers from four currently used depolymerization strategies in standard solvent systems. We further design new ternary and quaternary solvent systems that are predicted to further improve separation efficacy. On the basis of these predicted partition coefficients and empirical solvent selection criteria for CCC measurements, we suggest a range of solvent systems that would be suitable for the effective separation of aromatic lignin-derived products via CCC or similar liquid-liquid extraction methods.

Highly selective direct monofluorination of indoles and arenes was developed through an approach that allows site-specific solubility of substrate and fluorine source in the micelle. This approach was highly selective for a broad range of substrates with excellent functional group tolerance. Differences in binding constant and solubility of indoles and arenes in the micelle allowed the fine-tuning of selectivity. Control experiments suggested a radical pathway and provided insight into the role of micelles of the environmentally benign amphiphile PS-750-M. Dynamic light scattering experiments strongly indicated the site-specific solubility of the substrate and fluorine source. The methodology was successfully adapted to gram scale, and the E-factor established from a recycle study indicated that the process is environmentally responsible and sustainable.

Application In Synthesis of 3-Methylbenzoic acid. Wang, ZH; Wang, XN; Wen, D; Long, XL in [Wang, Zhi-hao; Wang, Xin-ning; Wen, Di; Long, Xiang-li] East China Univ Sci & Technol, Sch Chem Engn, State Key Lab Chem Engn, Shanghai, Peoples R China published Isophthalic acid production catalyzed by Co(II) together with phosphotungstic acid loaded on carbon modified with tartaric acid in 2020.0, Cited 34.0. The Name is 3-Methylbenzoic acid. Through research, I have a further understanding and discovery of 99-04-7.

Background Isophthalic acid (IPA) is commercially produced using the Co-Mn-Br catalyst system, which suffers from the shortcomings of the discharge of CH3Br and corrosion of equipment. It is necessary to develop a technology to avoid the pollution caused by bromide. The production of IPA from the oxidation ofm-xylene (MX) by air is realized under catalysis with H3PW12O40(HPW) loaded on carbon and cobalt. Results Tartaric acid has been used to improve the catalytic activity of the HPW@C catalyst. Experiments indicate that the best modification condition is calcining the carbon at 450 degrees C for 4 h after being soaked in a 2.0 mol L(-1)tartaric acid solution for 10 h. Surface characterization reveals that the tartaric acid modification leads to an increase in the acid groups and a reduction in the basic groups on the carbon surface. Conclusions The MX conversion obtained using the HPW@C catalyst prepared from modified carbon is 6.77% over that obtained using the HPW@C catalyst prepared from the original carbon. The IPA generated using the former is 71.1% over that generated using the latter. The catalytic activity of the HPW@C catalyst relies on its surface chemical characteristics and physical properties. The surface chemistry plays a more important role than the physical properties. (c) 2020 Society of Chemical Industry
