A nickel-catalyzed synthesis of an aryl nitrile via aryl exchange between an aromatic amide and a simple nitrile was developed. By using cheap, easy-to-handle, and low-toxic 4-cyanopyridine as the cyanating source, cyanation of various aromatic amides afforded an assortment of aryl nitriles including bioactive drugs and organic luminescent mols. in good yields. The reaction exhibited wide substrate scope, good functional group tolerance, and unique selectivity that were complementary to traditional methods. Moreover, two key nickel complexes formed by oxidative addition to each substrate are obtained and determined by X-ray crystallog., which gave strong support for the mechanism elucidations.

Li, Wenjuan published the artcileIron-Catalyzed C-C Bond Cleavage and C-N Bond Formation, Application of Bis(4-fluorophenyl)methane, the publication is Advanced Synthesis & Catalysis (2013), 355(1), 181-190, database is CAplus.

A novel approach for C-N bond formation was developed by iron-catalyzed C-C bond cleavage. Anilines and sulfonamides reacted smoothly with 2-substituted 1,3-diphenylpropane-1,3-diones to afford N-alkylation products, in which the 1,3-dicarbonyl group acts as a leaving group in the presence of an iron catalyst. E.g., in presence of FeCl₃.6H₂O, alkylation of 4-O₂NC₆H₄NH₂ by I gave 90% II. The reversible C-C bond cleavage plays a driving force to give the thermodynamically stable products. The method is complementary to the previous methods for C-N bond formation.

Lin, H. K. published the artcileProcess mineralogy of scandium and europium-containing iron-making slag, Application In Synthesis of 2016-56-0, the publication is Minerals & Metallurgical Processing (1997), 14(2), 18-20, database is CAplus.

During slow-cooling crystallization of ironmaking blast-furnace slags, most rare earth elements recrystallize in an artificial “mineral” identified as calcium cerite. Scandium (Sc) and europium (Eu), however, concentrate in a sheetlike “mineral”. The mineralogy of this sheetlike “mineral” was studied. It was identified as being in the mica group and was called a rare earth-bearing barium fluorophlogopite. It can be effectively recovered from the slag by flotation using dodecylammonium acetate or a combination of dodecylammonium acetate and sodium oleate as collectors.

The Au(I) complex of (2-morpholinophenyl)diadamantanylphosphine (Mor-DalPhos) as P,N-bidentate ligand and mesylate as counter ion catalyzed efficient oxidative transformations of various terminal alkynes into synthetically versatile [(methanesulfonyl)oxy]methyl ketones. The mild reaction conditions and high efficiency permit the one-pot synthesis of a range of valuable 2,4-disubstituted thiazoles by subjecting the resulting reaction mixture to a further condensation with thioamides under mild conditions.

The acceptorless dehydrogenation of diverse aromatic and aliphatic primary alcs. to corresponding carboxylic acids was accomplished by self-supported NHC-Ru single-site catalysts under mild reaction conditions. Besides broad substrates with excellent activity, selectivity and good tolerance to sensitive functional groups, the solid single-site catalyst could be recovered and reused for more than 20 runs without deactivation. Remarkably, up to 1.8 x 10⁴ turnover numbers could be achieved by this newly developed sustainable protocol in gram scale at low catalyst loading, highlighting its potential in industry.

Xu, Wenhao published the artcileDual Nickel- and Photoredox-Catalyzed Reductive Cross-Coupling of Aryl Halides with Dichloromethane via a Radical Process, Formula: C13H10F2, the publication is Organic Letters (2020), 22(21), 8643-8647, database is CAplus and MEDLINE.

The first catalytic strategy to harness a new chloromethane radical from dichloromethane under dual Ni/photoredox catalytic conditions has been developed. Compared with traditional two-electron reductive process associated with metallic reductants, this method via a single-electron approach can proceed under exceptionally mild conditions (visible light, ambient temperature, no strong base) and exhibits complementary reactivity patterns. It affords a broad scope of many functional groups, including alkenyl, which suffers cyclopropanation in previous routes. The diarylmethane-d2 compounds can be readily available with this transformation.

Glucose-responsive insulin represents a promising approach to regulate blood glucose levels. We previously showed that attaching two fluorophenylboronic acid (FPBA) residues to the C-terminal B chain of insulin glargine led to glucose-dependent solubility Herein, we demonstrated that relocating FPBA from B chain to A chain increased the baseline solubility without affecting its potency. Furthermore, increasing the number of FPBA groups led to increased glucose-dependent solubility
