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 Preparation of octa(alkoxy) azaphthalocyanines, published in 1999-12-31, which mentions a compound: 56413-95-7, Name is 5,6-Dichloropyrazine-2,3-dicarbonitrile, Molecular C6Cl2N4, Category: chiral-oxygen-ligands.

5,6-Bis(alkoxy)pyrazine-2,3-dicarbonitriles with methoxy-, ethoxy-, and propoxy-substituents were allowed to react with magnesium alkoxides to form the corresponding magnesium octaalkoxyazaphthalocyanines. The methoxy compound (I) was converted into the metal-free azaphthalocyanine and to the copper complex. The propoxy-substituted magnesium azaphthalocyanine was also converted to the metal-free azaphthalocyanine. Both of the propoxy compounds were readily soluble in organic solvents. The stable intermediate Me 2,3-dimethoxy-6-cyanopyrazine-5-carboximidate (II) was obtained both from reaction of 5,6-dichloropyrazine-2,3-dicarbonitrile with sodium methoxide in methanol, and in a sodium methoxide-catalyzed reaction of 5,6-dimethoxypyrazine-2,3-dicarbonitrile (III) with ammonia in methanol. II was converted into I with magnesium methoxide, and was therefore an intermediate between III and I.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 56413-95-7, is researched, Molecular C6Cl2N4, about N-Phenylfluorubine: one functional dye – chromophore, fluorophore, electron-acceptor and more, the main research direction is phenylfluorubine dye chromophore fluorophore electron acceptor.Name: 5,6-Dichloropyrazine-2,3-dicarbonitrile.

We are presenting a new derivative of the fluorubine family which exhibits highly fluorescent activity. 5-Phenyl-dihydro[5,6,7,12,13,14]-hexaazapentacene was synthesized via two subsequent cyclization reactions starting from com. available starting materials. Its properties were studied intensively via UV-vis and fluorescence spectroscopy, as well as cyclic voltammetry and quantum chem. calculations Furthermore, we found a strong pH-sensitivity, which influences the photo- and electrochem. properties heavily. Thereby, it is possible to tune its properties from an electron-rich donor to a highly electron-deficient acceptor material.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The synthesis of metal-free octaazaphthalocyanine derivatives containing bulky phenoxy substituents to prevent self-association, published in 2007-10-08, which mentions a compound: 56413-95-7, mainly applied to octaazaphthalocyanine phenoxy substituted preparation; pyrazinedicarbonitrile cyclocondensation, Application In Synthesis of 5,6-Dichloropyrazine-2,3-dicarbonitrile.

Octaazaphthalocyanines with eight phenoxy groups in the peripheral sites are prepared for the first time using the simple synthetic procedure of heating their pyrazine-2,3-dicarbonitrile precursor in quinoline. This process avoids transetherification, which has hindered previous attempts at preparing metal-free octaazaphthalocyanines. Metal-containing derivatives were also prepared by adding the appropriate metal salt to the reaction mixture Bulky iso-Pr or Ph groups at the 2,6-positions of the phenoxy substituents prevent self-association of the octaazaphthalocyanine cores even in the solid state.

COA of Formula: C6Cl2N4. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Cationic azaphthalocyanines bearing aliphatic tertiary amino substituents-Synthesis, singlet oxygen production and spectroscopic studies. Author is Zimcik, Petr; Miletin, Miroslav; Musil, Zbynek; Kopecky, Kamil; Kubza, Lukas; Brault, Daniel.

New cationic zinc azaphthalocyanines (AzaPc) were prepared using a statistical method of synthesis starting from 5,6-bis(2-diethylaminoethylsulfanyl)pyrazine-2,3-dicarbonitrile (A) and 5,6-bis(tert-butylsulfanyl)pyrazine-2,3-dicarbonitrile (B). All the six possible AzaPc derivatives were detected on TLC but only five of them were finally isolated using column chromatog. on silica (excluding AAAB type). The adjacent (AABB) and opposite (ABAB) isomers were well separated Singlet oxygen quantum yields (ΦΔ) were measured using the DPBF decomposition method. Values of ΦΔ in anhydrous DMF drastically decrease with the number of amino groups from 0.66 for BBBB type to 0.04 for AAAA type. The same dependence was observed in anhydrous DMF for the corresponding hydrochlorides. When DMF/water 95:5 added with HCl was used, the ΦΔ values for amino AzaPc increased to approx. 0.66. This suggests that solvation of the amino and Cl- ions plays an important role in the separation of the AzaPc mols. although no changes were found in UV-vis spectra. At least eight cationic charges are necessary for complete monomerization of AzaPc in water. Fewer charges lead to significant decrease of the absorption in the area of the Q-band and to pronounced dimeric character of the absorption spectrum.

COA of Formula: C6Cl2N4. 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. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Synthesis and solution studies on azaphthalocyanines with quaternary aminoethyl substituents.

A pyrazinedinitrile derivative carrying dimethylaminoethylsulfanyl groups at positions 5 and 6 was synthesized from 2-dimethylaminoethanethiol hydrochloride and 2,3-dicarbonitrile-5,6-dichloropyrazine. The dicarbonitrile gave magnesium azaphthalocyanine (MgAzaPc) when reacted with magnesium propoxide in propanol. The conversion of the MgAzaPc to a metal-free derivative was achieved by treatment with trifluoroacetic acid. Incorporation of transition metal ions into the inner core of azaphthalocyanine was accomplished by treatment of the metal-free derivative with metal acetates, i.e. Zn(OAc)2, Co(OAc)2. These azaphthalocyanines were converted into water-soluble quaternised products by reaction with Me iodide. Aggregation phenomena were followed for magnesium azaphthalocyanine with quaternisable dimethylamino substituents within a specific range of pH. The compounds were characterized by FTIR, 1H NMR, mass and UV-visible spectral data.
