Shi, Xian-Lei published the artcileA novel fiber-supported superbase catalyst in the spinning basket reactor for cleaner chemical fixation of CO2 with 2-aminobenzonitriles in water, Quality Control of 1885-29-6, the main research area is PEEK fiber supported catalyst spinning reactor cycloaddition aminobenzonitrile quinazolinedione.

The chem. fixation of CO2 with a more effective pathway is of great significance from the sustainable chem. viewpoint. Herein, a novel fiber-supported superbase was successfully synthesized by rooting 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) into the surface layer of com. available polyetheretherketone (PEEK) fiber and efficiently served as a heterogeneous catalyst for the conversion of CO2 in a sample spinning basket reactor. The resulting fiber samples were characterized detailedly by elemental anal., mech. property, FTIR spectroscopy and morphol. during both of the preparation and the utilization processes. Moreover, the fiber catalyst was applied in the spinning basket reactor under mild conditions (100°C and 1 MPa) for the cycloaddition of CO2 with a series of 2-aminobenzonitriles in water to obtain good to excellent yields of the corresponding quinazoline-2,4-(1H,3H)-diones (82-95%). In addition, the fiber-supported TBD in impellers of the agitation system was shown to be reused over 15 times without distinctly performance degradation, and stored on shelves remained equally active after at least up to 4 mo. Furthermore, the operation process was convenient and effective for scaling-up procedure and thereby the fiber catalyst has good prospects in industrial applications.

Zhao, Ziming published the artcilePreparation of a magnetic mesoporous Fe3O4-Pd@TiO2 photocatalyst for the efficient selective reduction of aromatic cyanides, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is iron oxide palladium titania mesoporous composite photoreduction photocatalyst hydrogenation.

Herein, a hierarchical magnetic mesoporous microsphere was successfully prepared as a photocatalyst via a simple and reproducible route. Typically, Pd nanoparticles (NPs) were evenly dispersed on the surface of a magnetic Fe3O4 microsphere and then coated with a porous anatase-TiO2 shell to form Fe3O4-Pd@TiO2. The core-shell structure could efficiently suppress the conglomeration of Pd NPs during the calcination process at high temperatures as well as the shedding of Pd during the catalytic reaction process in the liquid phase. The as-prepared photocatalyst was characterized by TEM, XRD, XPS, VSM, and N2 adsorption-desorption. Fe3O4-Pd@TiO2 exhibits high photocatalytic activity for the selective reduction of aromatic cyanides to aromatic primary amines in an acidic aqueous solution Moreover, this magnetic photocatalyst could be easily recovered from the reaction mixture by an external magnet and reused five times without significant reduction in its activity. The superior photocatalytic efficiency of the proposed photocatalyst may be attributed to its high charge separation efficiency and charge transfer rate, which are caused by the Schottky junction and large interface area. The results indicate that the strategy of coating the active noble metal sites with a mesoporous semiconductor shell has a significant potential for application in metal-semiconductor-based photocatalytic reactions.

Wang, Wenbo published the artcileTricycloquinazoline-containing 3D conjugated microporous polymers and 2D covalent quinazoline networks: microstructure and conductivity, Synthetic Route of 1885-29-6, the main research area is tricycloquinazoline conjugated microporous polymer covalent quinazoline network microstructure conductivity; gas adsorption hydrogen evolution reaction electrocatalyst.

Conjugated microporous polymers (CMPs) and covalent triazine frameworks (CTFs) with conjugated linkages and nanochannels have been showcased as a new platform in extensive fields. Here, by tuning the geometry of the N-rich skeleton tricycloquinazoline (TQ) unit, isomers of the 3D amorphous conjugated microporous polymer (TQ-CMP) and 2D laminar covalent quinazoline network (TQ-CQN) are synthesized. The derived diverse microstructure and elec. conductivity related to the applications of gas adsorption and the hydrogen evolution reaction (HER) are systematically discussed. TQ-CMP fabricated with an internal crosslinking network reveals a notable uptake of 25.6 wt% CO2 and of 2.91 wt% CH4 at 273 K and 1 bar, higher than most reported POP materials, which could be attributed to the higher BET surface area (781.0 m2 g-1) and dispersed pore size (1.1 nm to 13.1 nm) for guest mol. absorption. In contrast, both the modulated electronic structure of the precise π-conjugate planes and the vertically ordered one-dimensional channels endow TQ-CQN with more built-in catalytic sites and rapid electron transmission for the HER. Without any noble metal doping, the excellent catalytic activity and faster reaction kinetics of TQ-CQN are epitomized by the achieved lower overpotential of 80 mV and the Tafel slope of 40 mV dec-1.

Leijendekker, Leonardus H. published the artcileDevelopment, Scope, and Applications of Titanium(III)-Catalyzed Cyclizations to Aminated N-Heterocycles, Synthetic Route of 1885-29-6, the main research area is aminoindole aminopyrrole preparation fluorescence; imine cyclization titanium catalyzed; homogeneous catalysis; nitrogen heterocycles; reduction; titanium; umpolung.

The exceptionally mild conditions of a titanium(III)-catalyzed cyclization reaction paired with a convenient acid/base extraction was enabled the straightforward synthesis, isolation, and direct N-functionalization of amino heterocycles such as 3-aminoindoles I [R = Ph, 2-thienyl, 1-naphthyl, etc.] and -pyrroles. The unprotected heterocycles were ideal building blocks for the installation of aminated indoles and pyrroles into target mols., but their sensitivity had previously impeded their synthesis by modern catalytic methods. This full paper presented the development and extended scope of the new cyclization methodol. The transformation of the products into fused bis-indoles was also demonstrated along with the discovery of an unusual palladium-catalyzed reductive biphenyl coupling reaction. The titanium(III)-catalyzed cyclization had also been applied to the synthesis of substituted 3-iminoindolines, which were of potential interest for applications in natural product synthesis and exhibit tunable blue-to-green fluorescence properties.

Kukhta, Nadzeya A. published the artcileRevealing resonance effects and intramolecular dipole interactions in the positional isomers of benzonitrile-core thermally activated delayed fluorescence materials, Formula: C7H6N2, the main research area is dimethylacridin benzonitrile resonance dipole interaction fluorescence crystal structure.

We report on the properties of the three positional isomers of (2,7-di-tert-butyl-9,9-dimethylacridin-10(9H)-yl)benzonitrile, which are found to have comparable donor steric environments and donor-acceptor dihedral angles. An unexpected intramol. dipole interaction imparts a unique mol. geometry to the ortho-linked isomer, while comparison of the meta- and para-isomers uncovers how positional differences in acceptor strengths (a consequence of differences in aromatic π-system electron d.) lead to very different triplet harvesting and emission properties. These positional-isomer effects on TADF follow the well-known aromatic directing rules from organic synthesis, in keeping with their common origin arising from contributions of multiple electronic resonance structures. Understanding these positional effects and methods of dihedral control is critical to the future design of efficient TADF emitters.
