چکیده
In this study, Mn (III) salen complex was synthesized and immobilized onto the graphene oxide, which is modified by 3-chloropropyltrimethoxy silane. Heterogeneous catalyst was characterized by X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, fourier transform infrared spectra, nitrogen adsorption−desorption isotherm and atomic absorption spectroscopy. The catalytic activity of heterogeneous Mn (III) salen complex and comparison with its homogeneous analogue was studied for green oxidation of sulfide derivatives using aqueous 30% H2O2 as an oxidant in water media. The results showed that heterogeneous catalyst was highly efficient in this reaction and corresponding products were obtained in good to excellent yields. The advantages of this catalyst include short reaction times, no side reactions, easy and simple work up, mild reaction conditions and excellent selectivity. The heterogeneous nanocatalyst was reused for several runs without significant loss in activity and selectivity.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
