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 Cyclotetramerisations of sulfanyl substituted pyrazine-2,3-dicarbonitriles and phthalonitriles, the main research direction is sulfanyl pyrazine dicarbonitrile phthalonitrile preparation cyclotetramerization; zinc azaphthalocyanine phthalocyanine preparation.Product Details of 56413-95-7.
Pyrazine-2,3-dicarbonitriles, substituted with strong to moderate electron withdrawing sulfanyl groups, have been synthesized. One of these pyrazines, substituted with two 5-methyl-1,3,4-thiadiazole-2-sulfanyl groups, has shown significant anticancer reactivity. Two phthalonitriles, substituted with thiadiazole-sulfanyl groups have been synthesized. The reagents Zn(OAc)2 and Zn(quinoline)2Cl2, dissolved in quinoline, were reacted with the above monomers to obtain zinc azaphthalocyanines and phthalocyanines. Only zinc azaphthalocyanines with moderate electron withdrawing sulfanyl groups were obtained, whereas one phthalonitrile, substituted with two 5-methyl-1,3,4-thiadiazole-2-sulfanyl groups, gave the corresponding zinc phthalocyanine. Some pyrazine-2,3-dicarbonitriles, substituted with one 2-thienyl and one sulfanyl group, gave mixtures of the corresponding zinc azaphthalocyanine constitutional isomers. New compounds were characterised by elemental anal., UV-vis, IR, 1H and 13C NMR spectroscopies.
This literature about this compound(56413-95-7)Product Details of 56413-95-7has given us a lot of inspiration, and I hope that the research on this compound(5,6-Dichloropyrazine-2,3-dicarbonitrile) can be further advanced. Maybe we can get more compounds in a similar way.
