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 Dihydropyridines. XV. Reactions of some 3,5-dicyanopyridines with complex aluminum hydrides, published in 1968, which mentions a compound: 1195-58-0, Name is Pyridine-3,5-dicarbonitrile, Molecular C7H3N3, Computed Properties of C7H3N3.
The effect of 4 complex Al hydrides on the formation of the 1,2- and 1,4-dihydro derivatives was studied. The reductions were carried out in tetrahydrofuran or Et2O and the products separated by thin layer chromatography (the starting compound I, reagent, % yield of the mixture, product(s), and their ratio given): I (R1 = R2 = H), LiAlH4, NaAlH4, NaAlH2(OEt)2, 41-98, II (R1 = R2 = H), III (R1 = R2 = H), 44-7: 53-6; I (R1 = R2 = H), NaAlH2(OCH2CH2OMe)2, 12, II (R1 = R2 = H), 100%; I (R1 = H, R2 = Me), LiAlH4, 36, III (R1 = H, R2 = Me), 100%; I (R1 = H, R2 = Et), LiAlH4, 25, II (R1 = H, R2 = Et), III (R1 = H, R2 = Et), 91:9; I (R1 = Me, R2 = H), LiAlH4, 80, II (R1 = Me, R2 = H), 100%; I (R1 = R2 = Me), LiAlH4, 65, II (R1 = R2 = Me), III (R1 = R2 = Me), 43:57; and I (R1 = Me, R2 = Et), LiAlH4, 48, II (R1 = Me, R2 = Et), III (R1 = Me, R2 = Et), 20:80.
Although many compounds look similar to this compound(1195-58-0)Computed Properties of C7H3N3, numerous studies have shown that this compound(SMILES:N#CC1=CC(C#N)=CN=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
