| Outline of Final Research Achievements |
Chelating organosilyl ligands are known to stabilize the electron-rich coordinatively unsaturated transition metal complexes. In this project, highly-reactive iron complexes having chelating organosilyl ligand have been designed and synthesized. As the chelating organosilyl ligand, 1,2-bis(dimethylsilyl)benzene was selected, and we found that iron complex bearing this ligand can effectively capture dinitrogen between two iron centers. Then, iron dicarbonyl complex having 1,2-bis(dimethylsilyl)benzene ligand was synthesized, and we found that this complex shows excellent catalytic activity toward the reduction of various carbonyl compounds, hydrogenation as well as hydrosilylation of alkenes. This iron dicarbonyl complex also realized the C-H bond functionalization of arenes, and C-3 selective silylation of indole derivatives.
