“…Even though the activities against B. subtilis and S. aureus of the compounds are less than those of the penicillin, it is interesting that the activities against E. coli of the complexes are excellent and deserve further investigation. The trends in the present work are in accordance with those in the literature: the Schiff base complexes have stronger antibacterial activities than those of the parent Schiff bases [21][22][23].…”

A trinuclear complex, [Cu(Cu(l-Br) 2 L) 2 ], and a dinuclear complex, [Cu 2 (l-Cl) 2 L 2 ], have been synthesized with the tridentate Schiff base 1-[(2-morpholin-4-ylethylimino)methyl]-naphthalen-2-ol (HL), derived from 2-hydroxy-1-naphthyaldehyde and 4-(2-aminoethyl)morpholine. Both complexes have been characterized by physicochemical and spectroscopic methods. [Cu(Cu(l-Br) 2 L) 2 ] is a centrosymmetric bromide and phenolate oxygen-bridged trinuclear compound, while complex [Cu 2 (l-Cl) 2 L 2 ] is a centrosymmetric-chloride-bridged dinuclear compound. The central Cu(II) atom in [Cu(Cu(l-Br) 2 L) 2 ] is six-coordinated in an octahedral coordination, while other Cu(II) atoms in both complexes are five-coordinated in squarepyramidal coordinations. Both complexes and HL were tested in vitro for their antibacterial activities.

The synthesis, spectral, catalytic and antioxidant properties of ethyl-2-(2-hydroxy-3-methoxybenzylideneamino)-6-methyl-4,5,6-tetrahydrobenzo[b]thiophene-3-carboxylate (L) substituted iron(II), manganese(II), zinc(II), and ruthenium(II)-arene chlorides are described for the first time. The ligand and its metal complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, and spectral ( 1 H NMR, 13 C NMR, FT-IR, UV-Vis and Mass) techniques. The FT-IR spectra showed that the ligand can act as bidentate or tridentate. Magnetic moments and electronic spectral studies revealed an octahedral geometry for all the complexes obtained. The thermal behavior of the complexes showed that the water molecules were separated in the first step followed immediately by decomposition of the anions and ligand molecules in the subsequent steps. Ru(II) complex was used as catalysts for the transfer hydrogenation of ketones. At the same time, the effect of various bases such as NaOH, KOH, KOBu t and NaOAc as organic base were investigated in the transfer hydrogenation of ketones by 2-propanol as the hydrogen source.The complexes and ligand were tested in vitro for their antioxidant activity. The experimental results showed that Ru(II) complex had more potent antioxidant activities than Zn(II), Fe(II), Mn(II) complexes and parent ligand.

“…The authenticity of the substance was first established based on elemental analyses as well as the IR, 13 C and 1 HNMR spectra. 4 Reflection data were collected on a Rigaku AFC7S diffractometer using Mo Kα monochromated with graphite at 20.0˚C temperature and corrected for Lorentz and polarization effects. The structure was solved by a direct method (SIR 92), 5 and refined by full-matrix least-squares with anisotropic thermal parameters for the non-hydrogen atoms.…”

The chemistry of aminothiazoles and their derivatives has attracted the attention of chemists, since they exhibit important biological activity in medicinal chemistry. 1 2-Aminothazoles are known mainly as biologically active compounds with a broad range of activities and as an intermediates in the synthesis of antibiotics, well-known sulfa drugs, and some dyes. 2,3 Here, we report on the crystal structure of the title compound, shown in Fig. 1. To a solution of 0.76 g (10 mmol) of thiourea in 590 mL of absolute ethanol, a solution of 2.225 g (10 mmol) of 1-phenyl-1-methyl-3-(2-chloro-1-oxoethyl)cyclobutane in 20 mL of absolute ethanol was added dropwise at 60 -70˚C with continuous stirring. By monitoring the IR frequency of the carbonyl group of 1-phenyl-1-methyl-3-(2-chloro-1-oxoethyl)cyclobutane, completion of the reaction was easily seen. The solution was then made alkaline with an aqueous solution of NH3 (5%) to separate the pale-yellow 4-(1-phenyl-1-methylcyclobutyl-3-yl)-2-aminothiazole from the reaction mixture. The precipitate was filtered off, washed with an aqueous ammonia solution and water several times, dried in air and recrystallized from aqueous ethanol (1:3) by slow evaporation. The yield and melting point of the substance are 65%, and 174˚C, respectively. The authenticity of the substance was first established based on elemental analyses as well as the IR, 13 C and 1 HNMR spectra. 4 Reflection data were collected on a Rigaku AFC7S diffractometer using Mo Kα monochromated with graphite at 20.0˚C temperature and corrected for Lorentz and polarization effects. The structure was solved by a direct method (SIR 92), 5 and refined by full-matrix least-squares with anisotropic thermal parameters for the non-hydrogen atoms. In a later stage of the refinement, reflection data were corrected for absorption and extinction. All of the calculations were performed using the program system teXsan, 6 The crystal structure of 4-(1-phenyl-1-methylcyclobutyl-3-yl)-2-aminothiazole (C14H16N2S) has been determined by X-ray analysis. It crystallizes in the triclinic space group P1 -, with unit cell parameters: a = 10.4686(16), b = 11.9543(16), c = 5.9271(16)Å, α = 102.365(16), β = 92.120(16), γ = 65.302(15)˚, V = 657.1(2)Å 3 , Dc = 1.235 g/cm 3 , and Z = 2. The crystal structure was solved by direct methods and refined by full-matrix least squares to a final R-value of 0.041 for 2561 observed reflections.
