The summary and outlook of this book is described in the conclusion. Reduction and phosphonation with dialkyl phosphonate, vanadium-catalyzed or -induced dehalogenation, pinacol coupling, oxidative transformations of carbonyl compounds, ligand coupling, and oxidative halogenation are developed. For π, d, π-redox systems, coenzyme PQQ, polyanilines, and quinonediimines are used to achieve efficient catalysts and materials. The redox-active ligands are demonstrated to be useful in organic synthesis. Sumanene is synthesized for the first time, which is allowed to construct nonplanar π-conjugated systems and d, nonplanar π-conjugated ones. Chirality-organized spaces are developed by hybridization of organmetallic compounds and biomolecules like dipeptide, peptide, nucleobase, and DNA, which contributes to one of key researches in bioorganometallic chemistry. A combination of these fields will permit conceptionally new chemistry.
