Öğe Microwave-Assisted Synthesis, Characterization and Aggregation Properties of Novel Metallophthalocyanines containing 2-aminothiophenol moieties(Chem Soc Pakistan, 2018) Kantar, Cihan; Sahin, Onur; Sasmaz, SelamiThe microwave-assisted synthesis and characterization of novel peripherally 2-aminothiophenol substituted metallophthalocyanines (M: Ni(II), Zn(II)) have been reported for the first time in this study. All the new compounds were characterized by a combination of FT-IR, H-1-NMR, C-13-NMR, and UV/vis spectroscopy techniques. The crystal structure of compound (1) was also determined by the single crystal diffraction technique. Aggregation properties of metallophthalocyanines were investigated at different concentrations in DMSO.Öğe Microwave-assisted synthesis, characterization and spectral properties of non-peripherally tetra-substituted phthalocyanines containing eugenol moieties(Elsevier Science Bv, 2015) Kantar, Cihan; Sahin, Zarife Sibel; Buyukgungor, Orhan; Sasmaz, SelamiThe microwave-assisted synthesis and characterization of novel non-peripherally eugenol substituted metallophthalocyanines (M: Co(II), Ni(II), Cu(II), Zn(II)) have been reported for the first time in this study. All the new compounds were characterized by a combination of FT-IR, H-1 NMR, C-13 NMR, and UV/vis spectroscopy techniques. The crystal structure of compound (1) was also determined by the single crystal diffraction technique. Newly synthesized eugenol substituted phthalocyanines have more redshift Q bands (about 17-18 nm) than previously reported eugenol substituted phthalocyanines. Zinc(II)phthalocyanine (1d) has an extra absorption band at 746 nm that calling X band at UV/vis spectrum. (C) 2015 Elsevier B.V.

Microwave yields were higher than those of the conventional synthesis methods. All of these complexes are insoluble in polar solvents such as ethanol, ethyl acetate and chloroform. The characterization of the compounds was accomplished by elemental analysis, 1H NMR (for I and II), 13C NMR (for I and II), IR and UV-Vis spectral data. In addition, the structure of the starting material (I) was determined by single crystal diffraction.Öğe Synthesis, spectroscopic and structural studies of 4-Amino-3-(ethyl)-5-(4-chlorophenyl)-4H-1,2,4-triazole and 4-Amino-3-cyclopropyl-5-oxo-4,5-dihydro-1,2,4-triazole-1-yl-acetic acid ethyl ester(Elsevier Science Bv, 2014) Sahin, Onur; Kantar, Cihan; Sasmaz, Selami; Gumrukcuoglu, Nurhan; Buyukgungor, OrhanThe title compounds of 4-Amino-3-(ethyl)-5-(4-chlorophenyl)-4H-1,2,4-triazole (I, C10H11ClN4) and 4-Amino-3-cyclopropyl-5-oxo-4,5-dihydro-1,2,4-triazol-1-yl-acetic acid ethyl ester (II, C9H14N4O3), have been determined using X-ray diffraction techniques and characterized by IR, H-1 NMR and C-13 NMR. X-ray study shows that the title compounds both have strong intermolecular N-H center dot center dot center dot N hydrogen bonds. The molecules of! are linked into a two-dimensional framework structure by N-H center dot center dot center dot N and C-H center dot center dot center dot N hydrogen bonds which produce R-2(2)(8)R-4(4)(14)R-4(4)(15) chain of rings, while in II, the combination of N-H center dot center dot center dot N, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds along [100] generates a chain of edge-fused R-2(2)(10)R-2(2)(16)R-4(2)(14)R-4(4)(14) rings.
