Wu, Yi published the artcileLigand regulation to prepare an Fe, N, S tri-codoped hollow carbon electrocatalyst for enhanced ORR performance and Zn-air batteries, Synthetic Route of 91-15-6, the main research area is iron nitrogen sulfur carbon electrocatalyst ORR zinc air battery.

It is significant to explore high-efficiency, low-cost, and stable electrocatalysts for the oxygen reduction reaction (ORR) to substitute the precious metal platinum in electrochem. energy conversion devices. Materials with an Fe-Nx center are considered as promising catalysts to achieve this. Herein, a feasible SiO2-ZnCl2 template strategy is used to obtain nitrogen-sulfur-Fe co-doped periodic porous hollow carbon by calcining the Fe-based complexes with different ligands (1,10-phenanthroline, 2,2-bipyridine, and 1,2-dicyanobenzene). Owing to the introduction of the SBA-15 template and pore-forming agent ZnCl2, the as-prepared materials possess a large sp. surface area (SSA) and a well-defined hollow structure. Most importantly, different ligands have a crucial effect on the nitrogen content of the obtained materials, which in turn directly affects the metal active sites of ORR. The appropriate selection of 1,10-phenanthroline as the ligand creates abundant Fe-Nx active sites after the pyrolysis process. Therefore, the optimal hollow carbon (denoted as Z-CNS-Fe) derived from the complex of Fe2+ and 1,10-phenanthroline exhibits better ORR performance with a half-wave potential of 0.880 V, which is 30 mV higher than that of com. Pt/C (0.850 V). Beyond this, Z-CNS-Fe shows long-term stability and superior tolerance to methanol crossover. In addition, when Z-CNS-Fe was applied as the cathode of a primary Zn-air battery, the obtained metal-air cell provided a power d. as high as 141 mW cm-2, which exceeded that of com. Pt/C (114 mW cm-2). The high open-circuit voltage and satisfactory durability also indicate its potential practical applicability.

Ogunsipe, Abimbola published the artcileSynthesis, characterization and photostability studies on aluminium phthalocyanine chloride, Safety of Phthalonitrile, the main research area is aluminum phthalocyanine chloride microwave radiation photostability.

The synthesis, characterization and photostability studies of aluminum phthalocyanine chloride are hereby presented. Aluminum phthalocyanine chloride was synthesized by a solvent-free procedure involving microwave irradiation of a mixture of hydrated zinc chloride and 1,2-dicyanobenzene (phthalonitrile); the product was thoroughly purified and dried. The percentage yield was 83.4%. The characterization of the blue product was done via Fourier Transform IR Spectroscopy (FTIR) and UV-Visible spectrophotometry, and the results were satisfactory. In the FTIR spectrum, the formation of zinc phthalocyanine was confirmed by the band due to CN vibrations (around 2100 cm-1) which was present in the phthalonitrile (starting material), but absent in the product (aluminum phthalocyanine chloride). The UV-Visible absorption spectrum showed an intense signal at 672 nm and a weaker one around 350 nm. These bands are taken to be due to π→π* transitions within the phthalocyanine mol. The Beer-Lambert’s plot for the product resulted in a molar extinction coefficient value of 202,118 M-1 cm-1. Photodegradation studies showed that zinc phthalocyanine is very stable towards photoirradiation, with a rather small photodegradation value of 2.73 x 10-8.

Li, Hanning published the artcileTriarylamine-based porous coordination polymers performing both hydrogen atom transfer and photoredox catalysis for regioselective α-amino C(sp3)-H arylation, Safety of Phthalonitrile, the main research area is triarylamine based porous coordination polymer photocatalyst preparation; benzylamine regioselective preparation; amine benzonitrile alpha amino CH arylation coordination polymer photocatalyst.

Herein, a heterogeneous approach to combination of hydrogen atom transfer (HAT) and photoredox catalysis for regioselective C-H arylation of benzylamines was presented. The different mol. sizes and coordination modes of ligands, tricarboxytriphenylamine (H3TCA) and tris(4-(pyridinyl)phenyl)amine (NPy3), in one coordination polymer consolidated triarylamine (Ar3N) moiety into a special structural intermediate, which enhanced chem. and thermal stability of polymers and diminished structural relaxation during catalytic process. The inherent redox potentials of Ar3N moieties prohibited in situ formed Ar3N ·+ to earn an electron from C(sp3)-H nucleophiles, but allowed abstraction of a hydrogen atom from C(sp3)-H nucleophiles, enabling formation of C(sp3) · radical and cross-coupling reaction to proceed at most electron-rich sites with excellent regioselectivity. The new heterogeneous photoredox HAT approach skipped several interactions between transient species during typical synergistic SET/HAT cycles, demonstrating a promising redox-economical and reagent-economical heterogeneous platform that had not been reported for α-amino C-H arylation to form benzylamine derivatives Control experiments based on monoligand coordination polymers suggested that mixed-ligand approach improved photochem. and photophys. properties, providing important insight into rational design and optimization of recyclable photocatalysts for rapid access to complex bioactive mols. and late-stage functionalized pharmaceuticals.

Mills, L. Reginald published the artcileDesign of an Electron-Withdrawing Benzonitrile Ligand for Ni-Catalyzed Cross-Coupling Involving Tertiary Nucleophiles, Application In Synthesis of 91-15-6, the main research area is quaternary aryl nitrile synthesis; benzonitrile ligand nickel catalyzed cross coupling tertiary nucleophile; safety cyanide.

The design of new ligands for cross-coupling is essential for developing new catalytic reactions that access valuable products such as pharmaceuticals. In this report, we exploit the reactivity of nitrile-containing additives in Ni catalysis to design a benzonitrile-containing ligand for cross-coupling involving tertiary nucleophiles. Kinetic and Hammett studies are used to elucidate the role of the optimized ligand, which demonstrate that the benzonitrile moiety acts as an electron-acceptor to promote reductive elimination over β-hydride elimination and stabilize low-valent Ni. With these conditions, a protocol for decyanation-metalation and Ni-catalyzed arylation is conducted, enabling access to quaternary α-arylnitriles from disubstituted malononitriles. Safety: cyanide handling.

Davies, Alex M. published the artcileValorization of Ethanol: Ruthenium-Catalyzed Guerbet and Sequential Functionalization Processes, SDS of cas: 91-15-6, the main research area is ethanol ruthenium catalyst tandem guerbet alkylation; alc preparation.

A ruthenium-catalyzed tandem Guerbet-alkylation strategy for the valorization of ethanol was reported. The products of ethanol upgrading (higher-order alcs.) undergo subsequent C-C bond forming reactions with four carbon pronucleophiles and one ylide. Studies into catalyst design led to the development of ClRu(5-Mebpi)(PPh3)2 (bpi = 1,3-bis(2′-pyridylimino)isoindolate) as a highly efficient catalyst for producing biofuels and value-added chems. from ethanol via Guerbet and tandem Guerbet reactions. This catalyst affords 65% higher-order alcs. in short reaction times (2 h), providing the highest TON (155,890) and TOF (12,690 h-1) for a homogeneous catalyst reported to date.

Qi, Jing published the artcileNew Radical Borylation Pathways for Organoboron Synthesis Enabled by Photoredox Catalysis, Name: Phthalonitrile, the main research area is organoboron preparation photoredox catalysis mechanism electron transfer calculation borylation; crystal structure mol cyanoaryl boronate preparation; radical borylation photoredox catalysis; N-heterocyclic carbenes; borylations; organoborons; photocatalysis; radicals.

Radical borylation using N-heterocyclic carbene (NHC)-BH3 complexes as boryl radical precursors has emerged as an important synthetic tool for organoboron assembly. However, the majority of reported methods are limited to reaction modes involving carbo- and/or hydroboration of specific alkenes and alkynes. Moreover, the generation of NHC-boryl radicals relies principally on hydrogen atom abstraction with the aid of radical initiators. A distinct radical generation method is reported, as well as the reaction pathways of NHC-boryl radicals enabled by photoredox catalysis. NHC-boryl radicals are generated via a single-electron oxidation and subsequently undergo cross-coupling with the in-situ-generated radical anions to yield gem-difluoroallylboronates. A photoredox-catalyzed radical arylboration reaction of alkenes was achieved using cyanoarenes as arylating components from which elaborated organoborons were accessed. Mechanistic studies verified the oxidative formation of NHC-boryl radicals through a single-electron-transfer pathway.

Peng, Dao published the artcileHighly active and reusable copper phthalocyanine derivatives catalyzed the hydroxylation of (hetero)aryl halides, SDS of cas: 91-15-6, the main research area is metal phthalocyanine catalyst preparation; hetero aryl halide hydroxylation.

Authors have researched and developed a series of copper phthalocyanine derivatives as new highly active and reusable catalysts for the hydroxylation of (hetero)aryl halides. The perfluorinated copper phthalocyanine (CuPcF16) showed the highest activity for the hydroxylation of aryl iodide with an excellent yield (up to 98%) under low catalytic loading (0.5 mol% CuPcF16). Similarly, the hydroxylation of aryl bromides and aryl chlorides catalyzed by CuPcF16 also had high activity with 42-98% yield. Moreover, the recyclability of this catalyst can up to 6 times without significant loss in catalytic activity.

The direct borylation of two bis(pyrazolylimino)isoindoline chelates with BF3 and base under dry conditions gave two B adducts. These are ring-contracted analogs of biliazine and can be considered as subbiliazines, as they have bowl-shaped structures similar to subphthalocyanine. Addnl., a new iminooxoisoindoline BF2 complex was made from hydrolysis of the free base in the presence of BF3. The electronic structures of the free bases and subbiliazines were probed by d. functional theory (DFT) and time-dependent DFT (TDDFT) methods.
