Book excerpt: Organometallic Chemistry of Five-Membered Heterocycles explores the synthesis, coordination modes, reactivity of coordinated five-membered monoheterocycles, and organometallic complexes of their numerous derivatives, including chelating ligands, oligomers, and macrocycles. Beginning with the introduction of organometallic compounds, this book dives deep into the reactivity of coordinated five-membered monoheterocycles and the derivatives of fundamental ligands. This book is an ideal reference for researchers working in organometallic, heterocyclic, materials, or organic chemistry, and catalysis. The readers will gain a comprehensive understanding of modern synthetic methods, reactivity trends of heteroaromatic ligands, and the methods of modern materials construction.
