High-Valent Imido and Oxo Complexes in Electron Transfer, Atom Transfer, and Chlorite Catalysis

化学系的这一奖项支持普渡大学Mahdi Abu-Omar教授研究电子转移、质子耦合电子转移和氢原子转移反应。此外，还将探讨非血红素铁(IV)酰亚胺配合物对C-H胺化反应、丁二烯转移反应和氢原子转移反应的催化作用。还将研究一种模拟亚氯酸盐歧化酶并选择性地将亚氯酸盐歧化为氧气和无毒氯的分子催化剂。这项研究将研究电子和原子如何在分子间转移，并将研究酶亚氯酸盐歧化酶的分子模拟。这些研究涉及化学合成、催化、动力学和机理，这些研究将为博士后和研究生为学术、工业和政府职业做准备。与日本(大阪大学福津美教授)和韩国(梨花女子大学南教授)顶尖科学家的合作将进一步拓宽学生的科学视野。

This award in the Division of Chemistry supports research by Professor Mahdi Abu-Omar at Purdue University to study electron transfer, proton-coupled electron transfer, and hydrogen atom transfer reactions. In addition, the catalysis of C-H amination, nitrene transfer and hydrogen atom transfer reactions by nonheme iron(IV) imido complexes will be explored. A molecular catalyst that mimics the enzyme chlorite dismutase and is selective for chlorite dismutation to dioxygen and innocuous chloride will also be investigated. The manganese porphyrin system and nonheme catalysts that perform these reactions will be completely characterized.This research will study how electrons and atoms transfer between molecules and will investigate molecular mimics of the enzyme chlorite dismutase. These investigations involve chemical synthesis, catalysis, kinetics, and mechanisms, which will prepare postdoctoral and graduate students for academic, industrial, and government careers. Collaborations with leading scientists in Japan (Professor Fukuzumi, Osaka University) and Korea (Professor Nam, Ewha Womans University) will further broaden the students' scientific perspectives.
