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 Diastereoselective Synthesis of Pyrazolines by Metal-Free Rearrangement of Bicyclic Triazolines, published in 2020-10-31, which mentions a compound: 3393-45-1, Name is 5,6-Dihydro-2H-pyran-2-one, Molecular C5H6O2, Safety of 5,6-Dihydro-2H-pyran-2-one.

The metal-free preparation of diazoalkanes through the ring rearrangement of bicyclic triazolines was reported. Their use in 1,3-dipolar cycloaddition reactions with electron-withdrawing alkenes was investigated. This synthetic procedure allows differently substituted pyrazolines to be obtained in few steps and with high atom economy.

COA of Formula: C22H17N3. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Synthesis and magnetic study of μ1,1-azido-bridged dinuclear manganese(II) complexes based on tripyridyl ligands. Author is Yu, Ming-Ming; Ni, Zhong-Hai; Zhao, Chong-Chao; Cui, Ai-Li; Kou, Hui-Zhong.

Three azido-bridged MnII complexes [Mn2(N3)4(ttp)2] (1), [Mn2(N3)4(ttp-N3)2] (2) and [Mn2(N3)4(ttp-N3)2]3[MnIII(ttp-N3)(N3)3]2 (3), where ttp and ttp-N3 represent 4′-p-tolyl-2,2′:6′,2”-terpyridine and 4′-p-azidomethylphenyl-2,2′:6′,2”-terpyridine, were synthesized and characterized by single-crystal x-ray diffraction anal. and magnetic studies. The Mn ions in complexes 1 and 2 are coordinated by three N atoms of the ttp or ttp-N3 ligands, and they are connected by double end-on (EO) azide ligands; this forms a dinuclear MnII system with Mn-N-Mn bridging angles of 103.5 and 103.1°. The Br atoms of the -CH2Br ligands were replaced by azido groups during the formation of complexes 2 and 3. The structure of complex 3 comprises two structurally similar MnII dimers with double end-on bridging azide groups and one mononuclear MnIII structure. The bridging Mn-N-Mn angles in 3 are 104.2, 105.1, and 106.73°. Magnetic studies indicate intramol. ferromagnetic superexchange. The strength of ferromagnetic coupling within the Mn2 cores in 1-3 is dependent on the Mn-N-Mn bridging angles. The magnetic coupling constants for intermol. exchange are 2.46(4), 2.25(2), and 1.92(4) cm-1 for 1, 2, and 3, resp., from Hamiltonian H = -2JS1S2.
