Student Seminar Series: Professor X. Peter Zhang
Student Seminar Series
Professor Zhang's research program has centered on the development of fundamentally new catalytic systems for stereoselective chemical transformations and their applications for practical synthesis of organic molecules. Researchers in his group are particularly interested in developing one-electron catalytic approaches for homolytic radical chemistry to harness the vast potential of radical reactions for stereoselective construction of molecular structures. To this end, They have formulated “Metalloradical Catalysis” (MRC) as a concept to guide the development of general approaches for controlling reactivity and selectivity of various radical processes. For achieving enantioselective radical reactions, they have developed a family of unique chiral metalloradical catalysts based on structurally well-defined Co(II) complexes of D2-symmetric chiral porphyrins with tunable electronic, steric, and chiral environments. These Co(II)-based metalloradical catalysts have shown to be highly effective for a wide range of stereoselective organic reactions. Due to their distinctive radical mechanisms that involve unprecedented metal-stabilized radical intermediates, such as α-metalloalkyl radicals (also known as metallocarbene radicals) and ɑ-metalloaminyl radicals (also known as metallonitrene radicals), the Co(II)-based metalloradical systems enable addressing some long-standing challenges in these important organic transformations.
Professor Zhang earned his bachelor's degree from Anhui Normal University in China, his master's degree from Beijing Normal University in China, and his doctorate from the University in Pennsylvania. He was a post-doctoral researcher at the Massachusetts of Technology. Prior to joining the chemistry faculty at Boston College in 2015, he was a professor at the University of Tennessee and University of South Florida.
