Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Australian Journal of Chemistry called Laser-Based Formation of Copper Nanoparticles in Aqueous Solution: Optical Properties, Particle Size Distributions, and Formation Kinetics*, Author is Mulder, Ashley J.; Tilbury, Rhys D.; Wright, Phillip J.; Becker, Thomas; Massi, Massimiliano; Buntine, Mark A., which mentions a compound: 14389-12-9, SMILESS is C1(C2=NN=NN2)=CC=NC=C1, Molecular C6H5N5, Electric Literature of C6H5N5.

The authors explore the formation kinetics, optical absorption spectra, and particle size distributions of copper nanoparticles (CuNPs) formed by direct laser ablation from the bulk metal via a process the authors refer to as Laser Ablation Synthesis in Solution (LASiS). Comparisons are made between CuNPs formed in pure water vs. those formed in the presence of 1×10-4 M solutions of the N-donor ligands 4,4′-bipyridine (4,4’Bipy) and 1H-5-(4-pyridyl)tetrazole (T-4Py). CuNPs formed in pure water and in the presence of 4,4’Bipy display similar UV-visible absorption spectra and very similar particle size distributions. In comparison, CuNPs formed in the presence of T-4Py display significantly different absorption properties, with the surface plasmon resonance transition blue-shifted by ∼55nm, and a much smaller and narrower particle size distribution compared with the former samples. Based on previous literature reports, it is possible to ascribe these differences to differences in the CuNP surface oxidation states for samples prepared in the presence of T-4Py. However, an anal. of the formation kinetics of all three samples indicates near-identical behavior.

The isomeric 5-tetrazolylpyridines were prepared as analogs of the pyridinecarboxylic acids by interaction of the cyanopyridines with NH3 (I). Interaction of 2,6-dicyanopyridine (II) and I gave the tetrazole analog (III) of dipicolinic acid. Hydrogenation of the tetrazolylpyridines gave the corresponding 5-tetrazolylpiperidines, the analogs of the several isomeric piperidinecarboxylic acids. 2-Cyanopyridine (26 g.), 20 g. AcOH, and 22 g. NaN3 refluxed 4 days in 100 ml. BuOH, heated 2 days with a further 5 g. NaN3 and 10 g. AcOH (in other experiments 3- and 4-day heating periods gave approx. the same yields), the mixture diluted with 300 ml. H2O, the BuOH removed, the solution acidified, and the product separated gave 33.4 g. 5-(2-pyridyl)tetrazole (IV), m. 211-11.5° (decomposition) (H2O). Similarly, 3-cyanopyridine and I gave 91% 5-(3-pyridyl)tetrazole (V), m. 234-5° (decomposition) (H2O). Likewise, 4-cyanopyridine and I gave 93% 5-(4-pyridyl)tetrazole (VI), m. 253-4° (decomposition). II (27.5 g.) in 100 ml. BuOH refluxed 2 days with 38.2 g. NaN3 and 38 ml. AcOH then 2 days with 10 g. NaN3 and 20 ml. AcOH gave 45.6 g. III, m. 290° (decomposition)(H2O). IV (11 g.) in 150 ml. AcOH shaken 24 hrs. at 50 lb./sq. in. with 250 mg. PtO2 and H gave 10.5 g. 5-(2-piperidyl)tetrazole, m. 287° (decomposition); acetyl derivative m. 135.5-6.5° (H2O). For preparative purposes it was advantageous to form the acetyl derivative directly by hydrogenation of IV and after removal of the catalyst it was treated with Ac2O to give an over-all yield of 84%. V similarly hydrogenated gave an almost quant. yield of 5-(3-piperidyl)tetrazole, m. 296-7°(H2O); acetyl derivative m. 170-1° (iso-PrOH).

By assembling CoII ions and a combination of 5-(4-pyridyl)tetrazole (4-ptz) and formate ions, two distinct metal-organic frameworks, [Co3(4-ptz)5(HCOO)(H2O)2] and [Co3(4-ptz)4(DMF)2(HCOO)2] (DMF=N,N’-dimethylformamide), were synthesized. They were both characterized by single-crystal x-ray diffraction, IR spectroscopy, TGA, and powder X-ray diffraction. Structural analyses revealed that by slightly modulating the coordination environment of the trinuclear cobalt cluster, two complexes were formed featuring unusual six-connected nets reminiscent of a pyrazole-type linear trinuclear cobalt cluster as compared with the classic eight-connected bcu topol. In addition, [Co3(4-ptz)5(HCOO)(H2O)2] interacted strongly with CO2, with an adsorption enthalpy of 29.2 kJ mol-1, and in a selectivity study, the uptake ratios of CO2/N2 (from a 15:85 mixture) and CO2/CH4 (50:50 mixture) were 77.6 and 37.7, resp. Magnetic studies on both complexes revealed weak antiferromagnetic coupling between the CoII ions.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Chermahini, Alireza Najafi; Teimouri, Abbas; Momenbeik, Fariborz; Zarei, Amin; Dalirnasab, Zeinab; Ghaedi, Aseyeh; Roosta, Mostafa researched the compound: 5-(4-Pyridyl)-1H-tetrazole( cas:14389-12-9 ).COA of Formula: C6H5N5.They published the article 《Clay-catalyzed synthesis of 5-substituent 1-H-tetrazoles》 about this compound( cas:14389-12-9 ) in Journal of Heterocyclic Chemistry. Keywords: aryl substituted tetrazole preparation; arylnitrile sodium azide cycloaddition clay. We’ll tell you more about this compound (cas:14389-12-9).

In this study, the possibility of 5-substituted 1-H-tetrazoles synthesis using clays as catalyst was investigated. The reaction of a series of aromatic nitriles with sodium azide was catalyzed by montmorillonite K-10 or kaolin clays in water or DMF as solvent. Conventional heating or ultrasonic irradiation was used to promote reaction. The amount of nitrile to sodium azide mole ratio, amount of catalyst, reaction time, and solvent type were optimized. The versatility of this method was checked by using various nitriles, which showed reasonable yields of tetrazole formation. It was found that using nitriles with electron-withdrawing groups result in both higher yields and lower reaction times. The catalysts could be reused several times without significant loss of their catalytic activity. Compared to conventional heating, ultrasonic irradiation reduced reaction times and increased catalyst activity. The present procedure is green and offers advantages, such as shorter reaction time, simple workup, and recovery and reusability of catalyst. J. Heterocyclic Chem., (2010).
