We’ll tell you more about this compound (cas:1195-58-0).

A new and general nickel-catalyzed cyanation of hetero(aryl) chlorides using less toxic Zn(CN)2 as the cyanide source has been developed. The reaction relies on the use of inexpensive NiCl2·6H2O/dppf/Zn as the catalytic system and DMAP as the additive, allowing the cyanation to occur under mild reaction conditions (50-80 °C) with wide functional group tolerance. DMAP was found to be crucial for successful transformation, and the reaction likely proceeds via a Ni(0)/Ni(II) catalysis based on mechanistic studies. The method was also successfully extended to aryl bromides and aryl iodides.

Keywords: dihydropyridine hydride ion source thermodn. We’ll tell you more about this compound (cas:1195-58-0).

A series of 3,5-disubstituted 1,4-dihydropyridine derivatives including the derivative with two chiral centers, 6H (R2 = CH3, CH2Ph), as a new type of organic hydride source were synthesized and characterized. The thermodn. driving forces (defined as enthalpy changes or standard redox potentials) of the 6 elementary steps for the organic hydrides to release hydride ions in acetonitrile were measured by isothermal titration calorimeter and electrochem. methods. The impacts of the substituents and functional groups bearing the N1 and C3/C5 positions on the thermodn. driving forces of the 6 elementary steps were examined and analyzed. Moreover, the results showed that the reaction mechanism between the chiral organic hydride and activated ketone (Et benzoylformate) was identified as the concerted hydride transfer pathway based on the thermodn. anal. platform. These valuable and crucial thermodn. parameters will provide a broadly beneficial impact on the applications of 3,5-disubstituted 1,4-dihydropyridine derivatives in organic synthesis and pharmaceutical chem.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Pyridine-3,5-dicarbonitrile( cas:1195-58-0 ) is researched.Name: Pyridine-3,5-dicarbonitrile.Troschke, Erik; Leistenschneider, Desiree; Rensch, Tilo; Graetz, Sven; Maschita, Johannes; Ehrling, Sebastian; Klemmed, Benjamin; Lotsch, Bettina V.; Eychmueller, Alexander; Borchardt, Lars; Kaskel, Stefan published the article 《In Situ Generation of Electrolyte inside Pyridine-Based Covalent Triazine Frameworks for Direct Supercapacitor Integration》 about this compound( cas:1195-58-0 ) in ChemSusChem. Keywords: electrolyte pyridine covalent triazine framework supercapacitor; covalent triazine frameworks; cyclotrimerization; nitrogen heterocycles; supercapacitors; waste prevention. Let’s learn more about this compound (cas:1195-58-0).

The synthesis of porous electrode materials is often linked with the generation of waste that results from extensive purification steps and low mass yield. In contrast to porous carbons, covalent triazine frameworks (CTFs) display modular properties on a mol. basis through appropriate choice of the monomer. Herein, the synthesis of a new pyridine-based CTF material is showcased. The porosity and nitrogen-doping are tuned by a careful choice of the reaction temperature An in-depth structural characterization by using Ar physisorption, XPS, and Raman spectroscopy was conducted to give a rational explanation of the material properties. Without any purification, the samples were applied as sym. supercapacitors and showed a specific capacitance of 141 F g-1. Residual ZnCl2, which acted formerly as the porogen, was used directly as the electrolyte salt. Upon the addition of water, ZnCl2 was dissolved to form the aqueous electrolyte in situ. Thereby, extensive and time-consuming washing steps could be circumvented.
