Buchwald-Hartwig偶聯(lián)反應(yīng)目前已被廣泛應(yīng)用在有機(jī)合成中,在此類反應(yīng)中,配體起到至關(guān)重要的作用,采用不同的配體,反應(yīng)收率和效果均截然不同。百靈威聯(lián)合國(guó)際知名品牌STREM,研發(fā)出一種新型配體BrettPhos,它具有反應(yīng)條件溫和、純度高(≥98%)和收率高等優(yōu)點(diǎn),適用于Buchwald偶聯(lián)、Suzuki偶聯(lián)和Negishi交叉偶聯(lián)等反應(yīng)。

此種新配體已在化學(xué)科研中取得了令人矚目的成績(jī)。在JACS等高端學(xué)術(shù)期刊上,許多科學(xué)家均在發(fā)表的科技論文中提及,使用新配體Brettphos幫助他們?nèi)〉昧私艹龅目蒲谐晒?/p>
