Evergreen Context: Main-Group vs. Transition Metal Chemistry
Historically, transition metals have dominated organometallic chemistry due to their variable oxidation states and ability to form stable complexes with a wide range of ligands. Main-group metals, while abundant and often less expensive, have been less explored due to their higher reactivity and tendency to form polymeric structures. however, recent advances in ligand design and synthetic methodologies are enabling the stabilization of reactive main-group species, unlocking their potential in catalysis and materials science. This research builds upon a growing body of work demonstrating the
