Visible Light Generation Of High-Valent Corrole-Manganese(V)-Oxo Intermediates And Biomimetic Studies Of The Oxidation Of Organic Sulfides Catalyzed By Manganese Corroles With Iodobenzene Diacetate, Davis Ray Ranburger

Masters Theses & Specialist Projects

High-valent transition metal-oxo intermediates play essential roles as active oxidizing species in enzymatic and biomimetic catalytic systems. Extensive research has been conducted on a variety of transition metal catalysts being studied as models for the ubiquitous cytochrome P450 enzymes. In doing so, the production of enzyme-like oxidation catalysts and probing studies on the sophisticated oxygen atom transfer mechanism are taking place.

In this work, visible-light irradiation of highly-photo-labile corrole-manganese(IV) bromates and chlorates was studied in two corrole systems with differing electronic environments, i.e. 5,10,15-trisphenylcorrole (H3TPC) and 5,10,15- tris(pentafluorophenyl)corrole (H3TPFC). In both systems, homolytic cleavage of the O- …
