12月17日(月）に野依記念物質科学研究館 2F ケミストリーギャラリーにおきまして、Rinaldo Poli 先生をお招きし、GTR-IGER-RCMS セミナーを開催します。R. Poli 先生は新規な金属錯体触媒の開発と、有機合成反応やラジカル重合への応用で著名な先生です。今回は，錯体触媒による水素化反応の新機構を中心にご講演いただきます。皆様、ご来聴いただければ幸いです。
The catalyzed reduction (hydrogenation or transfer hydrogenation) of carbonyl compounds, particularly its enantioselective version, attracts considerable interest. Stimulated by Noyori's work on a Ru system, a prevailing mechanistic view calls from the simultaneous presence of a hydride and a deprotonatable donor function (typically an amine) for an outer-sphere transfer of H+ and H- from a neutral transition metal complex to the substrate. The presence of a strong base is typically needed for activity. However, many efficient catalysts do not contain deprotonatable ligands and still require the presence of a strong base for activity. Prof. R. Poli will introduce his original Ir and Ru catalytic systems and discuss their catalytic mechanisms.
