A crown-ether appended N-heteroacene 1 was reduced in the presence of NaBPh4 to the radical anion 2 by accepting one electron transferred from both the cathode and BPh4- as a reductant. The obtained radical anion 2 can function as a radical anion ligand to bridge two sodium ions to self-assemble into one-dimensional helical coordination polymers.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Studies on herbicidal 2,3-dicyanopyrazines. Part III. Structure-activity relationship in herbicidal activity of 5-chloro-2,3-dicyanopyrazines against barnyardgrass (Echinochloa curs-galli), published in 1983-12-31, which mentions a compound: 56413-95-7, Name is 5,6-Dichloropyrazine-2,3-dicarbonitrile, Molecular C6Cl2N4, Reference of 5,6-Dichloropyrazine-2,3-dicarbonitrile.

The herbicidal activities of 6-substituted 2,3-dicyano-5-chloropyrazines were evaluated and correlated with the previously reported substituent parameters π (hydrophobicity) and σp (Hansch, A., et al., 1973). Parameters π and π2 indicate that the hydrophobicity of the mol. is involved in the translocation of these compounds to the target site. The activity decreases with increasing electron-withdrawing property of the 6-substituent. The herbicidal activity varied parabolically with the change in π.

Phthalocyanines (Pc) and their aza-analogs azaphthalocyanines (AzaPc) (tetrapyrazinoporphyrazines) with eight n-octylsulfanyl or tert-butylsulfanyl peripheral substituents and different central metals (Mg, Zn, metal-free) were synthesized. Dimerization constants Kd and absorption spectra of pure monomeric and dimeric magnesium complexes in toluene were calculated using series of absorbances at different concentrations The bulky tert-butylsulfanyl substituents were found to be much better inhibitors of aggregation than long alkyl chains. Also Pc are less aggregated in organic solvents then AzaPc, short explanation is given. Singlet oxygen production of Pc and AzaPc was compared using dye-sensitized photooxidation of 1,3-diphenylisobenzofuran in pyridine. Both Pc and AzaPc showed similar activity not dependent on type of peripheral substitution. Zinc complexes of both Pc and AzaPc exceeded the magnesium ones and metal-free dyes in singlet oxygen production approx. twice.

Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Low-Power Laser Ignition of an Antenna-Type Secondary Energetic Copper Complex: Synthesis, Characterization, Evaluation, and Ignition Mechanism Studies.

In recent years, development of new energetic compounds and formulations, suitable for ignition with relatively low-power lasers, is a highly active and competitive field of research. The main goal of these efforts is focused on achieving and providing much safer solutions for various detonator and initiator systems. In this work, a new laser-ignitable compound, based on the 5,6-bis(ethylnitroamino)-N′2,N′3-dihydroxypyrazine-2,3-bis(carboximidamide) (DS3) proligand is prepared, characterized, and thermal and ignition properties are studied. This new energetic proligand was prepared in three steps, starting with 5,6-bis(ethylamino)-pyrazine-2,3-dicarbonitrile. Crystallog. studies of the DS3-derived Cu(II) complex (DS4) revealed a unique stacked antenna-type structure of the latter compound DS4 has an exothermal temperature of 154.5° and was calculated to exhibit a velocity of detonation of 6.36 km·s-1 and a detonation pressure of 15.21 GPa. DS4 showed properties of a secondary explosive, having sensitivity to impact, friction, and electrostatic discharge of 8 J, 360 N, and 12 mJ, resp. In order to study the mechanism of ignition by a laser (using a diode laser, 915 nm), a set of experiments are conducted that enabled to characterize a photothermal ignition mechanism. Furthermore, it was found that a single pulse, with a time duration of 1 ms and with a total energy of 4.6 mJ, was sufficient for achieving a consistent and full ignition of DS4. Dual-pulse experiments, with variable time intervals between the laser pulses, showed that DS4 undergoes ignition via a photothermal mechanism. Finally, calculating the chem. mechanism of the formation of the complex DS4 and modeling its anhydrous and hydrated crystal structures (d. functional theory calculations using Gaussian and HASEM software) allowed to pinpoint a more precise location of water mols. in exptl. crystallog. data. These results suggest that DS4 has potential for further development to a higher technol. readiness level and for integration into small-size safe detonator systems as for many civil, aerospace, and defense applications.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Synthesis and spectral properties of tetrapyrazinoporphyrazinato metal complexes derived from a sterically hindered phenol.Related Products of 56413-95-7.

The synthesis of metal-containing tetrapyrazinoporphyrazines (azaphthalocyanines) bearing eight bulky substituents at the peripheral positions is described. The key precursor was prepared using a nucleophilic aromatic substitution reaction between a sterically hindered phenol and 5,6-dichloropyrazine-2,3-dicarbonitrile. Thus, azaphthalocyanine (AzaPc) derived from 2,6-isopropyl-4-nitrophenol possesses substituents that are forced by steric constraints to adopt a non-planar conformation which drastically enhances the solubility of the macrocycles and inhibits efficient cofacial interaction of the macrocycles even in the solid state as evaluated by UV-visible and 1H NMR spectroscopic techniques. The intense absorption in the red visible region and photostability of these highly soluble and non-aggregated complexes enhance the dynamic activity and make these complexes potentially suitable for PDT.
