Splet鈴木反應 （日語： 鈴木反応 ，英語： Suzuki reaction ），也稱作 鈴木偶聯反應 （日語： 鈴木カップリング 、英語： Suzuki coupling ）、 鈴木－宮浦反應 （日語： 鈴木・宮浦反応 ，英語： Suzuki-Miyaura reaction ），是一個 有機 偶聯反應 ，是在 鈀 配合物催化下， 芳基 或 烯基 的 硼酸 或 硼酸酯 與 氯 、 溴 、 碘 代 芳烴 或 烯烴 發生交叉偶聯。 [1] [2] SpletThe reaction also works with pseudohalides, such as triflates (OTf), instead of halides, and also with boron-esters instead of boronic acids.. Relative reactivity: R 2-I > R 2-OTf > R 2 …
