| Outline of Final Research Achievements |
We synthesized group 9-11 metal complexes bearing new PS3-type or SiS3-type tripodal tetradentate ligands, and revealed their structures, reactivity and catalytic activity. A rhodium complex bearing the SiS3-type ligand, [RhCl(C8H13){Si(C6H4-2-S-i-Pr)3}], catalyzed hydrosilylation of phenylacetylene to give the corresponding Z-alkene at room temperature. On the other hand, the reaction at 50 °C resulted in the formation of the corresponding E-alkene as a main product. It is interesting that the selectivity is changed by the reaction temperature. In addition, a rhodium(I) complex bearing the PS3-type ligand, [RhCl{P(C6H4-2-S-i-Pr)3}], readily reacted with O2 to afford the corresponding Rh-O2 complex. It is expected that the rhodium(I) complex can activate O2 molecule.
