  Cobalt(III)-Catalyzed Functionalization of Unstrained Carbon–Carbon Bonds through β-Carbon Cleavage of Alcohols

  摘要：

  We demonstrate that a simple Co(III)-complex can efficiently catalyze the cleavage of unstrained C-C bonds via the beta-carbon elimination of secondary and tertiary alcohols bearing a directing group. The cobalt-aryl intermediate generated under the reaction conditions can be trapped by different electrophiles to generate a new carbon carbon bond. Some essential features of this new Co-based mechanistic manifold were revealed by preliminary mechanistic studies.

  Rh催化的C ？C通过中间核糖体对醛和亚胺的亲核加成，裂解苄基/烯丙醇以生产苄基/烯丙基胺或其他醇

  摘要：

  我们报告了三种转化：1）从联芳基甲醇直接转化为联芳基甲胺；2）从一种联芳基甲醇直接转化为另一种联芳基甲醇；3）从烯丙基醇直接转化为烯丙基胺。这些变换是基于吡啶基定向的Rh催化的Ç 仲醇的C键裂解和随后的除CX（X = N或O）的双键。反应条件简单，不需要添加剂。C的驱动力C键裂解是稳定的rhodocycle中间体的形成。也可以使用其他定向基团，例如吡唑基，尽管其效率不如吡啶基。我们对转化1进行了深入研究，发现：1）底物范围广，富含电子的醇和缺乏电子的亚胺更有效；2）作为离去基团，醛对CC键断裂或整个转化均无显着影响；3）机理研究（中间分离，原位NMR光谱研究，竞争反应，同位素标记实验）表明：i）C在这些条件下，C裂解非常有效。ii）在rhodocycle中间体与质子化副产物苯基吡啶之间存在平衡；iii）所述rhodacycle中间体亚胺的添加步骤是比C慢 Ç裂解和rhodacycle和苯基之间的平衡;

  1,1‐Biarylmethanol substrates undergo reductive cleavage of the CC bond in the presence of a cationic RhIII catalyst and H2 (see scheme; DG=directing group). Various functional groups are tolerated in the reaction system. Preliminary studies indicate that a five‐membered rhodacycle intermediate, which then converts into a RhIII hydride species for the reduction, is involved in the catalytic cycle.

  imines was slower than the CC cleavage and the equilibrium between the rhodacycle and phenylpyridine; iv) the whole transformation was a combination of two sequences of CC cleavage/nucleophilic addition and CC cleavage/protonation/CH activation/nucleophilic addition, with the latter being perhaps the main pathway. We also demonstrated the first example of cleavage of an C(alkenyl)C(benzyl) bond
