請求幫我翻譯一段烯烴復(fù)分解反應(yīng)摘要！最好使用被動語態(tài) 謝謝
|
||
| 烯烴復(fù)分解反應(yīng)（Olefin metathesis reactions）是指在金屬卡賓配合物與烯烴催化反應(yīng)下，反應(yīng)中烯烴雙鍵斷裂重組得到新的烯烴和新的卡賓配合物的過程。目前已研究出烯烴復(fù)分解反應(yīng)的各種基本類型并廣泛應(yīng)用于醫(yī)藥和聚合物工業(yè)之中，烯烴復(fù)分解反應(yīng)涉及金屬催化劑存在下烯烴雙鍵的重組，有效的催化劑使得合成過程更便捷，生產(chǎn)效率更高，相對于其他反應(yīng)，該反應(yīng)副產(chǎn)物及廢物排放少，更加環(huán)保。目前研究出復(fù)分解反應(yīng)類型及催化劑，復(fù)分解反應(yīng)催化劑是復(fù)分解反應(yīng)能否實現(xiàn)的核心問題，烯烴復(fù)分解反應(yīng)的研究歷城，從發(fā)現(xiàn)到得到廣泛應(yīng)用，實際上也就是催化劑發(fā)展、改進(jìn)的過程。所以，復(fù)分解反應(yīng)催化劑的設(shè)計、改進(jìn)十分重要。烯烴復(fù)分解反應(yīng)具有反應(yīng)條件溫和，產(chǎn)率較高以及具有出色的官能團(tuán)適應(yīng)性等性質(zhì)，所以具有非常廣泛的應(yīng)用空間，目前已廣泛的應(yīng)用于天然產(chǎn)物的全合成、特性材料合成、制藥等領(lǐng)域。 |

Olefin metathesis reactions refer to a process of obtaining new olefin and new carbene through alkene double bond breakage and recombination under the catalytic reactions of metal carbene composition and olefin. At present, various basic types of Olefin metathesis reactions have been studied and widely used in Pharmaceutical and polymer industries. Olefin metathesis reactions involve in recombination of alkene double bond in the presence of metal catalysts, and the effective catalysts make the synthesis process more convenient and higher productive efficiency. Compared with other reactions, the by-products and the discharge of wastes are rare, which is more environmental protected. Currently, the type of metathesis reactions and catalysts have been studied. Metathesis catalysts are the core issues of whether metathesis reactions can be achieved. The research course of olefin metathesis reactions, from discovery to wide use, is actually the process of catalysts development and improvement. Therefore, the design and improvement of metathesis catalysts are extremely important. Olefin metathesis reactions have properties of mild reaction conditions, higher productivity and excellent functional adaptation, thus having very broad application space, which has now been widely used in many fields such as total synthesis of natural products, properties materials synthesis, and pharmacy. （僅供參考。。） |
