Schiff-oxime ligands characterized by the existence and participation of iminic-and oximic azomethine groups in coordination with metal ions [1-3]. Metal complexes of imineoxime have various applications in different scientific fields. It has been used as antimicrobial [4], antibacterial [5], antifungal [5,6] as well as anticancer [7]. Some of Schiff oxime derivatives have been used in extraction [8] and spectrophotometric determination [9] of metal ions. Imine-oxime complexes have been also found used as catalysts for selective oxidation of alcohols to ketones and aldehydes [10]. EXPERIMENTAL Chemicals have been procured from Fluka and Sigma-Aldrich. Shimadzu (FT-IR), 4800S spectrophotometer has been used to get FTIR spectra of prepared compounds (4000-400 cm-1 , KBr). Cary 100con. spectrophotometer has been used for electronic spectra of prepared compounds at wavelength 200-800 nm. Stuart digital SMP30 apparatus used for measuring melting points of compounds. Mass spectrum of H2L was performed on GC-MS QP-2010 (Shimadzu). NMR spectra of H2L in DMSO-d6 were recorded by Bruker DMX-500 spectrophotometer (300 MHz). Phoenix-986 AA spectrophotometer has been used to estimate the metal ions percentages.
The polymers derived from heterocyclic rings like imidazole was prepared and supported to produce catalytic active supported catalyst. This catalyst was characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), H NMR and UV-visible spectroscopy. The catalyst showed high catalytic activity in the oxidation of cyclohexene and cyclopentene under optimized conditions. In this work cyclohexene and cyclopentene were selected as model alkene for determination the capacity of the prepared imidazole polymer catalyst under optimized conditions of temperature and time of reaction. The catalyst could be readily separated from the catalytic system using uploading 3-5 milligrams of Copper(II), Nickel(II) and Cobalte(II) ions with the surface of polymer the conversion them to nano-particle which are identified by x-ray diffraction. For this research, a statistical method called Response Surface Methodology (RSM) has been used to economize the number of experiments and their meaningful interpretation. The effect of metallated polymer with Copper(II), Nickel(II) and Cobalte(II) were taken to increase the efficiency of oxidation. Optimization results for 0.33 mmole cyclohexene and cyclopentene showed that maximum oxidation efficiency 90. % was achieved at the optimum conditions: catalyst amount 350 mg, temperature 70.0, time 3.30 h and oxidant= 5.25 m mole.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
