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, Journal of Porphyrins and Phthalocyanines called Syntheses of Octa(dialkylamino)azaphthalocyanines, Author is Morkved, Eva H.; Kjosen, Helge; Ossletten, Hege; Erchak, Nikolai, the main research direction is azaphthalocyanine dialkylamino copper nickel preparation; transition metal dialkylamino azaphthalocyanine preparation; pyrazine diiminoimide cyclization dialkylamino azaphthalocyanine preparation.Product Details of 56413-95-7.
Ni(II) octa(4-morpholinyl)- (11a) and Cu(II) octa(1-pyrrolidinyl)- (11b) azaphthalocyanines were prepared from the corresponding pyrazine diiminoimides (10). The precursor pyrazine dicarbonitriles (2) gave 6-cyanopyrazine-5-alkyl carboximidates (3-9) as stable intermediates when reacted with NH3 and catalytic amounts of Na alkoxide in alcs. 3-9 Were converted to the diiminoimides 10 upon reflux in PrOH or BuOH for several hours. This unusual reaction pattern was observed for pyrazine-2,3-dicarbonitriles (2) with morpholine, thiomorpholine, piperidine or pyrrolidine substituted in the 5- and 6-positions.
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.
