About the research project
The oxidation of readily accessible and inexpensive aromatic compounds by powerful oxidants can result in the generation of valuable dearomatized molecules with a wide range of applications in synthetic chemistry, biology, and pharmaceuticals. However, the most often employed oxidants are extremely hazardous and typically require extreme conditions to facilitate the reactions. These disadvantages significantly restrict the use of such oxidants, particularly on a large scale, and make controlling the oxidative processes difficult, raising the cost of the desired products. To circumvent these disadvantages, one solution is to employ hypervalent iodine oxidants, which are environmentally benign, sustainable, recyclable, and very affordable. However, in most situations, hypervalent iodine reagents are inert towards oxidation of unactivated aromatic compounds, and unique approaches must be developed to activate them for this purpose. The aim of this project is to create such innovative approaches by utilizing our experimental and theoretical expertise to unlock the latent reactivity of hypervalent iodine compounds and to manufacture important dearomatized products at a significantly lower economic and energy cost. In this regard, we discovered a novel mechanism named "ligand-promoted iodine(V)-mediated oxidation" (LPIMO) using computational chemistry tools. This mechanism can serve as a foundation for understanding how to activate hypervalent iodine(V) reagents such as DMP and IBX towards the oxidation of nonactivated aromatic compounds. Currently, the approach is confined to the oxidation of electron-rich pyrroles with DMP; however, this study will allow us to use the synergy between experimental and theoretical skills to broaden the scope of the synthetic methods.
