    Bippyphos配体家族的简化合成和交叉偶联应用
    摘要:
    我们描述了Bippyphos,1的有效制备方法。Bippyphos的关键前体5是通过二锅2的一锅溴化反应,然后用吡唑烷基化并与苯肼缩合制备的。5的锂化并用二叔丁基氯膦捕获,得到Bippyphos,1。使用这种方法,我们已经制备了Bippyphos的几种衍生物,以探测该膦配体家族的结构和活性之间的关系。我们还证明了这些配体在钯催化的胺化反应和其他交叉偶联反应中的效用。

    An efficient procedure for palladium-catalyzed coupling reactions of (hetero)aryl bromides and chlorides with primary aliphatic alcohols has been developed. Key to the success is the synthesis and exploitation of the novel bulky di-1-adamantyl-substituted bipyrazolylphosphine ligand L6. Reaction of aryl halides including activated, nonactivated, and (hetero)aryl bromides as well as aryl chlorides with
    已开发出钯催化的(杂)芳基溴化物和氯化物与脂肪伯醇偶联反应的有效方法。成功的关键是合成和开发了新型庞大的二-1-金刚烷基取代的双吡唑基膦配体 L6。芳基卤化物,包括活化的、非活化的和(杂)芳基溴化物以及芳基氯化物与伯醇反应,以高产率得到相应的烷基芳基醚。值得注意的是,伯醇在仲醇和叔醇存在下的官能化具有出色的区域选择性。

    the efficient preparation of Bippyphos, 1. The key precursor to Bippyphos, 5, was prepared via a one-pot bromination of diketone 2 followed by alkylation with pyrazole and condensation with phenylhydrazine. Lithiation of 5 and trapping with di-tert-butylchlorophosphine afforded Bippyphos, 1. Using this approach we have prepared several derivatives of Bippyphos to probe the structure and activity relationships
