Redox-Active Pincer Ligands

This review aims to provide a comprehensive overview of the emerging field of redox-active pincer ligands. As such, following a short general introduction on ligand-centred redox activity, the recent literature is discussed in two separate sections. The first deals with ligand platforms that predominantly display reductive chemistry from the 'parent' scaffold; the second focusses more on systems that readily undergo oxidative chemistry. Fundamental stoichiometric reactivity as well as, where explored, catalytic applications will be discussed. This combined survey hopefully inspires the exploration and uncovering of many new avenues within the realm of redox-active pincer chemistry.
