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: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Inorganica Chimica Acta called Syntheses, reactivity, structures and photocatalytic properties of mononuclear ruthenium(II) complexes supported by 1,4,7-trimethyl-1,4,7-triazacyclononane (Me3tacn) ligands, Author is Qian, Bing-Feng; Wang, Jun-Ling; Jia, Ai-Quan; Shi, Hua-Tian; Zhang, Qian-Feng, the main research direction is preparation mononuclear ruthenium trimethyltriazacyclononane bipyridine complex; crystal structure mononuclear ruthenium trimethyltriazacyclononane bipyridine complex; cyclic voltammetry mononuclear ruthenium trimethyltriazacyclononane bipyridine complex; water slitting photocatalyst mononuclear ruthenium trimethyltriazacyclononane bipyridine complex.COA of Formula: C12H12N2.
Treatment of ruthenium(II) precursor [(Me3tacn)Ru(DMSO)Cl2] (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane, DMSO = dimethylsulfoxide) (1) with concentrated HCl in the presence of air afforded a ruthenium(III) complex [(Me3tacn)RuCl3·H2O] (2). Reaction of 2, 2,2′-bipyridine or substituted 2,2′-bipyridine, and zinc metal powder in the presence of sodium perchlorate gave the corresponding cationic aquaruthenium(II) complex [(Me3tacn)Ru(R-bpy)(H2O)](ClO4)2 (bpy = 2,2′-bipyridine, R = H, 3; 4,4′-Me2, 4; 5,5′-Me2, 5; 4,4′-di-tBu, 6). The hydrate ligand in complexes 3 and 5 could be substituted by acetonitrile or pyridine forming complexes [(Me3tacn)Ru(5,5′-Me2-bpy)(MeCN)](ClO4)2 (7) and [(Me3tacn)Ru(R-bpy)(py)](ClO4)2 (py = pyridine, R = H (8), R = 5,5′-Me2 (9)), resp. Interaction of [(Me3tacn)Ru(bpy)(H2O)](PF6)2 with phenylacetylene in methanol afforded a ruthenium-carbene complex [(Me3tacn)(bpy)Ru:C(OMe)CH2Ph](PF6)2 (10). All complexes are well characterized by IR, UV/visible, and NMR spectroscopies. The mol. structures of 1, 1·2H2O, 4·2H2O, 7, 8, 9, and 10 were also established by single-crystal X-ray diffraction. The photocatalysis properties of complexes 3, 5, and 6 for H2 evolution by water splitting were also studied.
