  successful synthesis of arylated stibine 3 a in a scale of 34.77 g demonstrates high synthetic potential of this transformation. The formed stibines (R3Sb) were then used for the palladium‐catalyzed carbon–carbon bond forming reaction with aryl boronic acids [R−B(OH)2], giving biaryls with high selectivity, even the structures of two organomoieties (R and R′) are very similar. Plausible catalytic pathways

  镍催化的halostibines交叉偶联，开发了一种形成锑-碳键的策略。该方法已被用于从相应的环状和非环状halostibines合成各种三芳基和二芳基烷基stibines。该方案显示了广泛的底物范围（72个实例），并且与各种官能团（如醛，酮，烯烃，炔烃，卤代芳烃（F，Cl，Br，I）和杂芳烃）兼容。成功合成规模为34.77 g的芳基锑化3a证明了这种转化的高合成潜力。然后将形成的stibines（R 3 Sb）用于与芳基硼酸[ RB （OH）2的钯催化的碳-碳键形成反应，从而产生具有高选择性的联芳基，甚至两个有机基团（R和R'）的结构也非常相似。根据控制实验提出了合理的催化途径。

  Biaryl scaffolds were constructed via Ni-catalyzed aryl C-O activation by avoiding cleavage of the more reactive acyl C-O bond aryl carboxylates. Now aryl esters, in general, can be successfully employed in cross-coupling reactions for the first time. The substrate scope and synthetic utility of the chemistry were demonstrated by the syntheses of more than 40 biaryls and by constructing complex organic molecules. Water was observed to play an important role in facilitating this transformation.
