Research interests

Organometallic chemistry, bond activation (C-H, Si-H, B-H..), asymmetric synthesis and catalysis, multi-step synthesis, nanoparticles.

Current research

Our current work is dedicated to the development of new simple and easy to use low valence cobalt complexes in order to study their reactivity in bond activation reactions (C-H, Si-H, B-H, H-H) followed by hydro-elementation reactions. We also explore their reactivity in the soft and reasoned synthesis of nanoparticles while trying to understand the mechanisms involved in the processes. We are also developing research on the reactivity of niobium complexes in cyclization and hydro-elementation reactions.
