Cyclo-Pn ligands are carbon-free analogues to aromatic organic ligands. They have lone electron pairs, which are reactive towards Lewis acidic transition metals to give various coordination. According to a recent review article co-authored by researchers at the University of Regensburg, these are a few reasons cyclo-Pn ligand complexes are so important to the field of organometallic chemistry. In this Q&A blog, we talk to two of the co-authors on that paper, Dr Peresypkina and Dr Virovets, about the team’s work, trends they found, and potential applications for the compounds.
