Author is Haldon, Estela; Alvarez, Eleuterio; Nicasio, M. Carmen; Perez, Pedro J..

The use of structurally well-characterized Cu(I) species as precatalysts in C-N and C-S bond forming reactions is described. Two new dinuclear Cu(I) complexes containing two isomeric ligands of bis(7-azaindolyl)methane were synthesized and fully characterized by NMR and x-ray diffraction studies. Both Cu(I) species exhibit a 1:1 Cu/L ratio and were used as precatalysts in the N-arylation of 2-pyrrolidinone and S-arylation of thiols with aryl iodides. The complexes efficiently catalyze these cross-coupling reactions, affording high yields of products under mild conditions.

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.
