| Research Abstract |
This research project was intended to establish the methodology for the construction and modification of the reaction field of metal complex. The reaction field created on the metal complex can be modified by appropriately changing ligands. Ten researchers working in a variety of fields have been divided into the following four groups.
1. Creation of Highly Functioned Mononuclear Active Species
Takashi ito, Kohtaro Osakada, and Sanshiro Komiya
2. Construction of Sterically and Electronically Controlled Multimetallic Reaction Field
Hiroharu Suzuki, Kiyashi Isobe, and Kazuyuki Tatsumi
3. Conversion of Organic Substrates in the Highly Controlled Metal Complex Reaction Field
Tamotu Takahashi and Yasuo Wakatsuki
4.Theoretical Approach directed toward Control of Reaction Field
Nobuaki Koga and Shigeyoshi Sakaki
The first group achieved activation of CO_2, Si-C bond, and N-H bond by using coordinatively unsaturated transition metal complexes. The second group developed systematic synthetic method of metal cluster complexes. Di- and trinuclear polyhydride complexes of ruthenium could activate a variety of organic substrates including alkanes and unprecedented type of selective C-H and C-C bonds cleavage was performed. A new class of clusters with Rh-S-W framework were systematically synthesized. A novel organic transformation involving zirconacyclopentene as synthetic intermediate and redox reaction of NO on hexanuclear carbonyl clusters were performed by the third group. Ab initio MO studies of several transition metal complex-catalyzed reactions such as olefin polymerization and hydrosilation were done by the fourth group.
