| Outline of Final Research Achievements |
N,C,S-pincer iron(III) carbonyl complexes with two phosphorus ligands were synthesized, and the CO releasing properties induced by visible to near-IR light were investigated. Iron complexes of S,N,C,S-tetradentate ligands were synthesized by introducing a pendant thioether arm, which is reversibly replaced by CO. Hydride iron complexes were detected in the reaction of diphosphine-bridged diiron thiolate complexes with dihydrogen. Iron carbonyl complexes stabilized by metallacycles were synthesized from quinolyl-substituted thiophene derivatives.

| Academic Significance and Societal Importance of the Research Achievements |
地球上に豊富に存在し、環境適合性の高い鉄を利用した機能性物質の開発は、持続可能な社会を築くうえで有用である。自然界の酸化還元酵素では鉄－硫黄骨格が重要な役割を果たしているが、その仕組みを人工触媒に組み込むことは非常に難しい。本研究では、メタラサイクルで安定化したチオラート鉄錯体を多く開発しており、酵素に見られる鉄－硫黄骨格の特徴を生かした触媒開発への展開が期待できる。
