    芴的锂化/烷基化导致各种9-烷基芴(烷基= Me,Et,iPr,-Pr,-C18H25)> 95%的收率,对此进行锂化和与R2PC1的反应(R = Cy,iPr,tBu )生成9-烷基,9-PR2-芴,它们构成了富电子且庞大的膦配体。在有机溶剂中的芳基氯化物和芳基溴化物的Sonogashira,Suzuki和Buchwald-Hartwig反应中测试了原位形成的钯-膦配合物([Na2PdCl4] 、,盐,碱,底物)。在1-mol%的Pd催化剂下,在100-120摄氏度下,芳基氯化物的Sonogashira偶联可导致> 90%的收率。芳基氯的Suzuki偶联通常需要在100摄氏度的二恶烷中加入0.05摩尔%的Pd催化剂,以定量形成产物。为了在水中进行“绿色”交叉偶联反应,使9-乙基芴基二环己基膦在硫酸中反应,生成相应的2-磺化phospho盐。通过使用这种水溶性催化剂进行的活化芳基氯的Suzuki偶联仅需要0

    Sulfonated, water-soluble imidazolium and imidazolinium salts were synthesized and the respective Pd-complexes with N,N'-bis(2,6-dialkyl-4-SO(3)(-)-phenyl)imidazol-2-ylidene and N,N'-bis(2,6-dialkyl-4-SO(3)(-)-phenyl)-4,5-dihydroimidazol-2-ylidene ligands were applied in aqueous Suzuki coupling reactions of aryl chlorides.

    The Pd-catalyzed Suzuki coupling reactions of a series of aryl chlorides and aryl bromides containing basic nitrogen centers with arylboronic acids in water in the absence of added base are reported. The reactions proceed either partially or entirely under acidic conditions. After surveying twenty-two phosphorus ligands, high yields of products were obtained with aryl chlorides only when a bulky ligand
    据报道,在不添加碱的情况下,中一系列含碱性氮中心的芳基化物和芳基化物与中的芳基硼酸进行催化的Suzuki偶联反应。反应在酸性条件下部分或全部进行。在调查了二十二个配体后,只有在庞大的配体2-(二叔丁基-膦基)-1-苯基-1 H上,芳基化物才能获得高收率的产品。使用了吡咯(cataCXium®PtB)。相反,在不存在添加的碱和添加的配体的情况下,芳基化物产生高产率的产物。为了完全探索酸性条件下的Suzuki偶联过程,使用几种模型底物在缓冲的酸性介质中进行了一系列反应。在cataCXium®PtB的存在下,4-苄基胺在缓冲的pH 6.0下产生了高收率的产品;在缓冲pH 5.0和更低的条件下,产量急剧下降。产量的下降归因于Pd-配体络合物的分解,这是由于在较酸性的性介质中配体的质子化所致。相反,在没有添加配体的情况下,4-基-2-氯吡啶在缓冲的pH 3.5和4下产生定量产率
