| Ruthenium-catalyzed Olefin metathesis in water using thermo-responsive diblock copolymer micelles Noriyuki Suzuki,* Ken Watanabe, Chirika Takahashi, Yuko Takeoka, Masahiro Rikukawa Current Organic Chemistry, 2023, accepted. DOI: |
| Abstract: Ruthenium-catalyzed olefin metathesis reactions were conducted in water in the presence of thermo-responsive block copolymers that form micelles. The block copolymers were prepared by living radical polymerization and consisted of a thermo-responsive segment and a hydrophilic segment. The former segment included poly(N-isopropylacrylamide) or poly(N,N-diethylacrylamide), and the latter poly(sodium 4-styrene sulfonate), poly(sodium 2-acrylamido-2-methylpropanesulfonate) or poly(ethylene glycol). Homometathesis, cross-metathesis and ring-closing metathesis reactions proceeded to afford the products in moderate to good yields. Extraction efficiency from the reaction mixture was also studied.Keywords: olefin metathesis; ruthenium catalysts; poly(N-isopropylacrylamide); thermo-responsive polymer; reaction in water. |

| 温度応答性ジブロックコポリマーミセルを用いる水中でのルテニウム触媒オレフィンメタセシス反応 鈴木 教之,* 渡邉 謙, 高橋知理香, 竹岡 裕子, 陸川 政弘 Current Organic Chemistry, 2023, accepted. DOI: |
| 温度応答性ジブロックコポリマーミセルを用いて、ルテニウム触媒によるオレフィンメタセシス反応を水中で行った。ホモメタセシス、クロスメタセシス、閉環メタセシスなどの反応が進行し、生成物の回収効率は水のみで実施した反応より高くなった。 |
