NiS nanoparticles modified black TiO2 hollow nanotubes (NBTNs) are successfully synthesized via surface hydrogenation and the facile solvothermal method. The unique structure with intensified surface and interface characteristics endow NBTNs with more catalytic sites, and increase charge carrier separation efficiency with an extended charge lifetime, overwhelmingly promoting its photocatalytic performance. The resultant NBTNs possess a relatively high surface area and pore size of 89 m2 g-1 and 9.8 nm, resp. The resultant NBTNs exhibit an excellent solar-driven photocatalytic hydrogen rate (3.17 mmol h-1 g-1), which is almost as high as that of Pt as cocatalyst, in which the apparent quantum yield of 5.4% (420 nm) is recorded for the NBTNs sample. Moreover, the turnover number can be up to 116 000 within 48 h and the turnover frequency is 2400 for NiS. This novel strategy could provide a better understanding of cocatalyst photocatalytic mechanisms, and a scheme simultaneously regulating the morphol. and structure of photocatalysts for promoting H2 generation.

《Sustainable Ligand-Free Heterogeneous Palladium-Catalyzed Sonogashira Cross-Coupling Reaction in Deep Eutectic Solvents》 was written by Messa, Francesco; Dilauro, Giuseppe; Perna, Filippo M.; Vitale, Paola; Capriati, Vito; Salomone, Antonio. Application of 90-14-2 And the article was included in ChemCatChem in 2020. The article conveys some information:

The com. available and cheap Pd/C was found to promote Sonogashira couplings in the environmentally friendly choline chloride/glycerol eutectic mixture in the absence of external ligands. Under heterogeneous conditions, (hetero)aryl iodides ArI (Ar = naphthalen-1-yl, thiophen-2-yl, 3-chlorophenyl, etc.) were successfully coupled with both aromatic and aliphatic alkynes RCCH (R = trimethylsilyl, pentyl, Ph, etc.) in yields ranging from 50 to 99% within 3 h at 60°C. The aforementioned catalytic system proved to be effective also towards electron-rich iodides, which are notoriously known to be poorly reactive in Pd-catalyzed Sonogashira coupling reactions. The eutectic mixture and the catalyst could easily and successfully be recycled up to four times with an E-factor as low as 24.4.

《STM apparent height measurements of molecular wires with different physical length attached on 2-D phase separated templates for evaluation of single molecular conductance》 was written by Iizuka, Tomoya; Shimizu, Daiki; Matsuda, Kenji. Recommanded Product: 1-Bromo-4-iodobenzene And the article was included in RSC Advances in 2020. The article conveys some information:

Single mol. conductance of mol. wires is effectively evaluated by the combination of STM apparent height measurement and a 2-D phase separation technique.

A 1,2-difunctionalization of an unactivated alkene, imidoyl-carbamoylation were developed through a palladium-catalyzed four-component cascade reaction involving aryl iodide, alkenyl isocyanide, CO and amine. Continuous migratory insertion of three different functionalities to the Pd(II) intermediate generated from the previous step took place in a well-defined sequence. Four chem. bonds, including three C-C bonds and one C-N bond, were formed in this cascade process, leading to a convenient and convergent access to acetamides substituted with five- to seven-membered cyclic ketoimines. In addition, an extra C-N bond was formed through in-situ or postreaction cyclization of the amido NH to the ketoimine moiety, providing a facile one-pot access to pyrrolo-fused heterocycles.

The article was titled 《Radial Type Ring Opening of Sulfonium Salts with Dichalcogenides by Visible Light and Copper Catalysis》, and you may find the article in Organic Letters.Computed Properties of C6H4ClI The information in the text is summarized as follows:

Herein, a copper-catalyzed, blue-light-induced free radical type ring opening of sulfonium salts with dichalcogenides has been initially developed. The developed method features an inexpensive copper catalyst and a broad substrate scope, affording practical access to alkyl chalcogenides in high yields. This reaction presents a novel ring-opening model of sulfonium salts, which breaks the limitation that only the nucleophilic ring-opening reaction could form C-heteroatom bonds and C-C bonds.
