請求幫我翻譯一段烯烴復分解反應摘要！最好使用被動語態(tài) 謝謝
|
|||
| 烯烴復分解反應（Olefin metathesis reactions）是指在金屬卡賓配合物與烯烴催化反應下，反應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分解反應的各種基本類型并廣泛應用于醫(yī)藥和聚合物工業(yè)之中，烯烴復分解反應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，該反應副產(chǎn)物及廢物排放少，更加環(huán)保。目前研究出復分解反應類型及催化劑，復分解反應催化劑是復分解反應能否實現(xiàn)的核心問題，烯烴復分解反應的研究歷城，從發(fā)現(xiàn)到得到廣泛應用，實際上也就是催化劑發(fā)展、改進的過程。所以，復分解反應催化劑的設(shè)計、改進十分重要。烯烴復分解反應具有反應條件溫和，產(chǎn)率較高以及具有出色的官能團適應性等性質(zhì)，所以具有非常廣泛的應用空間，目前已廣泛的應用于天然產(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。。） |
