Author is Yuan, Shang-Fu; Luyang, Heng-Wang; Lei, Zhen; Wan, Xian-Kai; Li, Jiao-Jiao; Wang, Quan-Ming.

Cu hydrides are very useful in hydrogenation reactions. The authors report a stable Stryker-type Cu hydride reagent protected by hemilabile phosphines: [Cu8H6(dppy)6](OTf)2 (Cu8-H, dppy = diphenylphosphino-2-pyridine). The metal core of this cluster has a bicapped octahedral configuration, and the Cu-bound hydrides each triply bridges over a triangular face of the octahedron. This cluster is attractive due to its facile preparation and excellent stability under ambient conditions. The comparable activity and selectivity both in the stoichiometric and catalytic reactions make Cu8-H a promising alternative to Stryker’s reagent.

A facile and simple method for synthesis of structurally diverse 3-sulfenylindole derivatives by direct sulfenylation of indoles using diaryl disulfides in the presence of mol. iodine as a catalyst. The sulfenylation proceeded well in both dichloromethane and dimethylsulfoxide. The reaction proceeded much faster in good yield in DMSO at 70°, as compared to dichloromethane at room temperature or in acetonitrile under reflux conditions and without iodine no conversion was observed With 5 mol% of iodine, a reasonable conversion was observed in dichloromethane as compared to acetonitrile at room temperature and under reflux conditions while 10 mol% gave an excellent conversion in DCM and DMSO. The simplified procedure has several merits in terms of ease of operation, mild conditions, excellent yields, atom economy and regioselectivity.

Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-(5-Bromothiophen-2-yl)pyridine, is researched, Molecular C9H6BrNS, CAS is 123784-07-6, about Synthesis and antibacterial activity of 9-oxime ether non-ketolides, and novel binding mode of alkylides with bacterial rRNA. Author is Liang, Jian-Hua; Lv, Wei; Li, Xiao-Li; An, Kun; Cushman, Mark; Wang, He; Xu, Ying-Chun.

We report a series of new 9-oxime ether non-ketolides, including 3-hydroxyl, 3-O-acyl and 3-O-alkyl clarithromycin derivatives, and thiophene-containing ketolides, e.g. I. Unlike previously reported ketolide 1a, none of them is comparable to telithromycin. A mol. modeling study was performed to gain insight into the binding mode of alkylides with bacterial rRNA and to rationalize the great disparity of their SAR. The results clearly indicated the alkylides with improved antibacterial activity might possess a novel binding mode, which is different from clarithromycin and the alkylides with poor activity.

Computed Properties of C17H14NP. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about N-(α-ferrocenyl)ethylphthalimide as single redox couple for non-aqueous flow batteries. Author is Hwang, Seunghae; Kim, Hyun-seung; Ryu, Ji Heon; Oh, Seung M..

To establish highly soluble single redox couple for non-aqueous flow batteries, N-(α-ferrocenyl)ethylphthalimide (α-FcEtPI) is derived from a promising single redox couple, N-ferrocenylphthalimide (FcPI), by inserting an α-Me group between the ferrocenyl and phthalimide moieties. The resulting material (α-FcEtPI) shows the maximum solubility of 0.81 M in 1.0 M tetrabutylammonium tetrafluoroborate (TBABF4) in 1,3-dioxolane at 25 °C. This notable increase in solubility (vs. 0.3 M for FcPI) is attributed to the disruptive effect of the α-Me group on mol. packing in a solid state. α-FcEtPI exhibits two stable redox reactions at E1/2 = 0.01 V and -1.97 V (vs. Fc/Fc+), thus functioning as a single redox couple with working voltage (Ewk) of 1.98 V. Considering the solubility and working voltage, the theor. energy d. of α-FcEtPI is calculated as 21.06 W h L-1 (vs. 7.8 W h L-1 for FcPI). The cell data of 0.6 M α-FcEtPI in 1 M TBABF4 in 1,3-dioxolane electrolytes, indicates remarkably high Coulombic efficiency (97.8%) and excellent cycle retention.

Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about Installation of Minimal Tetrazines through Silver-Mediated Liebeskind-Srogl Coupling with Arylboronic Acids. Author is Lambert, William D.; Fang, Yinzhi; Mahapatra, Subham; Huang, Zhen; am Ende, Christopher W.; Fox, Joseph M..

Described is a general method for the installation of a minimal 6-methyltetrazin-3-yl group via the 1st example of a Ag-mediated Liebeskind-Srogl cross-coupling. The attachment of bioorthogonal tetrazines on complex mols. typically relies on linkers that can neg. impact the physiochem. properties of conjugates. Cross-coupling with arylboronic acids and a new reagent, 3-((p-biphenyl-4-ylmethyl)thio)-6-methyltetrazine (b-Tz), proceeds under mild, PdCl2(dppf)-catalyzed conditions to introduce minimal, linker-free tetrazine functionality. Safety considerations guided the authors’ design of b-Tz which can be prepared on decagram scale without handling hydrazine and without forming volatile, high-N tetrazine byproducts. Replacing conventional Cu(I) salts used in Liebeskind-Srogl cross-coupling with a Ag2O mediator resulted in higher yields across a broad library of aryl and heteroaryl boronic acids and provides improved access to a fluorogenic tetrazine-BODIPY conjugate. A covalent probe for MAGL incorporating 6-methyltetrazinyl functionality was synthesized in high yield and labeled endogenous MAGL in live cells. This new Ag-mediated cross-coupling method using b-Tz is anticipated to find addnl. applications for directly introducing the tetrazine subunit to complex substrates.
