Copper makes the difference: Developing Sustainable Photoredox Catalyzed Transformations Synthetic organic chemistry undertakes significant efforts to develop new catalytic transformations that utilize greener reagents and avoid stoichiometric additives. In this regard, visible-light photoredox catalysis offers a unique activation mode of molecules, which serves as an alternative to many thermal transition-metals catalyzed reactions. The vast majority of photoredox-catalyzed processes capitalizes on heavy metals, namely, Ru(II) or Ir(III)-complexes which can serve as single electron oxidants or reductants in their photoexcited states.

Low-valent silicon complexes and their analogues: surprising and peculiar behaviors For over ten years, we have been developing the chemistry of low-value silicon complexes with a unique phosphine ligand system. These complexes exhibit special properties (somewhat like transition metals). When this ligand system is applied to synthesize other stable complexes of low-valent main-group elements, they also exhibit peculiar and surprising behaviors, allowing us to develop even more amusing chemistry. In my talk, I'll present some recent results on their chemistry.
