Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 56413-95-7, is researched, SMILESS is N#CC1=NC(Cl)=C(Cl)N=C1C#N, Molecular C6Cl2N4Journal, Coloration Technology called Synthesis and solution studies on azaphthalocyanines with quaternary aminoethyl substituents, Author is Kobak, Rabia Z. Uslu; Gul, Ahmet, the main research direction is magnesium cobalt zinc substituted azaphthalocyanine preparation UV.Synthetic Route of C6Cl2N4.
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.
