Buchwald–Hartwig 偶聯(lián)反應(yīng)是鈀催化和堿存在下胺與鹵代芳香化合物的交叉偶聯(lián)反應(yīng)。是合成芳胺化合物的重要方法。百靈威可提供種類齊全的Buchwald–Hartwig 偶聯(lián)反應(yīng)相關(guān)試劑,并備有充足現(xiàn)貨。

◆ 發(fā)展歷程

Buchwald–Hartwig 這一類型的反應(yīng)最早是由烏克蘭的 Lev M. Yagupolskii 等在 1986 年發(fā)現(xiàn)的。此后美國的 Buchwald 和 Hartwig 兩個團隊又分別在 1994 年重新發(fā)現(xiàn)這個反應(yīng)。耶魯大學(xué)的 Hartwig 等用的是對溴甲苯與三丁基錫基胺之間的偶聯(lián)。[1]

麻省理工學(xué)院的 Buchwald 等用的則是間溴苯甲醚與另一三丁基錫胺之間的偶聯(lián),見下:[2]

其后又發(fā)展了第二代的 Buchwald–Hartwig 反應(yīng),即用游離胺和強堿,代替最早使用的氨基錫烷。[3]

此外,反應(yīng)中的芳鹵也可為擬芳鹵三氟甲磺酸的酚酯所代替,胺可為伯胺或仲胺,胺上的取代基可以為任何有機基團。鈀催化劑常為鈀磷配合物,如四( 三苯基膦) 鈀,也可為三( 雙亞芐基丙酮)二鈀[4]等其他鈀配合物。反應(yīng)用堿一般為雙( 三甲硅基)氨基鈉或叔丁醇鹽。
