Resumen de Metalloporphyrins as oxidation catalysts: moving toward 'greener' chemistry in the inorganic chemistry laboratory
Rose A. Clark, Anne E. Stock, Edward P. Zovinka
Training future chemists to be aware of the environmental impact of their work is of fundamental importance to global society. To convince chemists to embrace sustainability, the integration of green chemistry across the entire chemistry curriculum is a necessary step. This experiment expands the reach of green chemistry techniques into the inorganic laboratory curriculum. Students utilize a metalloporphyrin catalyst with hydrogen peroxide to facilitate the production of cyclooctene oxide eliminating the need for the environmentally harmful iodosylbenzene catalyst. Both chloroiron(III) tetraphenylporphyrin and chloroiron(III) tetra(pentafluorophenyl)porphyrin are incorporated into the experiment to allow comparison of catalytic activity. Product characterization includes UV-visible spectroscopy and gas chromatography-mass spectrometry.
