چکیده

Developing the catalytic procedures for the selective oxidation of organic substrates in the clean conditions is environmentally important and many research efforts have been paid to this topic in the last decades [1]. Molecular oxygen as a standard green oxidant can be used for the oxidation processes and great interest have been dedicated to improving new strategies for the activation of O2 in the green catalytic systems. Unfortunately, using molecular oxygen in the catalytic systems facing some difficulties and the main important problem is because of the spin-forbidden law.However, there are some promising strategies, like using photosensitizers [2] and light aldehydes [3] which can active molecular oxygen in the oxidation systems. Metalloporphyrins as biomimetic catalysts for green oxidation systems, can overcome the problems and activate molecular oxygen to oxidize organic compounds in the mild conditions and various metalloporphyrins have been widely used in the selective aerobic oxidation of hydrocarbons.In this work, several supported and unsupported metalloporphyrines have been synthesized and characterized by standard methods and used as significant catalysts for the aerobic oxidation of olefins in the absence of any additives in the mild conditions at room temperature.

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.
