Outline of Final Research Achievements |
In this study, the author investigated the synthesis of [(arene) RuCl2]2 having polymer-bound arene ligand, the complexation of small molecular ligand with it and its application to the catalytic reactions. When the reaction of polymer P-1 with [(ethyl 4-methylbenzencarboxylate)RuCl2]2 was performed in a mixed solvent of cyclohexane and chlorobenzene to afford dark green powder. 1H NMR analysis of the resulting powder implied the possibility of the formation of proposed ruthenium complex P-l-Ru. Treatment of P-l-Ru with a small molecular phosphine ligand Dppe (diphenylphosphinoethane) afforded yellowish powder. Both P-l-Ru and P-l-Ru(dppe) showed the recyclable catalytic activity on the transfer hydrogenation of acetophenone to 1-phenylethanol.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、高分子担持芳香族の配位したルテニウム錯体の合成を、とくにその汎用性の高さに焦点を当てて研究した。各種合成法を検討したが、置き換わりやすい電子不足型芳香族配位ルテニウム錯体と、電子豊富型芳香族を持ったMerrifield Resinとの配位子交換反応により、高分子担持ルテニウム錯体の合成に成功した。まだ、定量的とはではないが、合成錯体は合成反応に触媒活性を有すること、さらなる配位子を含む錯体に変換可能なことを示しており、各種高分子担持触媒の合成のこれからに光明を与えたと考えられる。
