The Role of Monoanionic Aryl Pincer Ligands in the Stabilization of Group 14 Metallylenes

Pincer ligands have an important role in stabilizing group 14 metallylenes. The particular structure of the aryl pincer ligands makes them a unique ligand platform. This review is focused on presenting monoanionic metallylenes stabilized by aryl pincer-type ligands, described so far in the literature, with focus on their synthesis, structural features, and reactivity. Throughout this work, the close correlation between structure and reactivity is highlighted, as well as the manner in which this influences the stability of the compounds and their potential applications.
