氮杂环卡宾系列产品
氮杂环卡宾(NHC)被归类为有机实体,其特征是在氮杂环系统内的价壳中只有6个电子的二价碳原子(称为卡宾)。自从1991年Arduengo第一次分离得到稳定的游离氮杂环卡宾后,其作为一种高效的有机催化剂得到了迅速的发展,由于氮杂环卡宾的极性反转特性,使它在有机合成中构建复杂分子占有举足轻重的地位。氮杂环卡宾可以和过渡金属形成稳定的C-M键,与传统的配体相比,更加稳定且富电子,具有独特的立体效应和电子效应。传统的钯、铜等过渡金属络合物参与的反应必须在无氧条件下进行,而金属氮杂环卡宾催化剂由于具有较高的稳定性,甚至可以在有氧条件下进行一些交叉偶联反应。
氮杂环卡宾作为辅助配体具有以下优点:1)NHC复合物的强金属-卡宾键有利于紧密的结合动力学,从而提高中心金属的稳定性;2)比对应的膦催化剂具有更高的活性,有利于钯催化芳基氯化物的氧化加成率;3)与N原子键合的位阻基团的存在有助于从钯中对产物进行还原性消除;4)NHC配体的活性可通过远程引入电子导向取代基来进行修饰,也可通过取代基修饰获得手性、固定化和水溶解性。
