  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.

  Carboxylate assistance proved to be the key for the success of efficient cobalt(III)‐catalyzed CH cyanations. Thus, an in situ generated cationic cobalt complex was identified as a versatile catalyst for the site‐selective synthesis of various aromatic and heteroaromatic nitriles with ample substrate scope.

  事实证明，羧酸盐辅助是有效的钴（III）催化的CH氰化成功的关键。因此，原位生成的阳离子钴络合物被认为是用于多种底物范围广泛的各种芳族和杂芳族腈的定点合成的通用催化剂。

  A chelation-assisted palladium-catalyzed cascade bromination/cyanation reaction of 2-arylpyridine and 1-arylpyrazole C−H bonds has been developed. Notably, the reaction employs K3[Fe(CN)6] as a safe and nontoxic cyanide source, providing aromatic nitriles in moderate to good yields in one-pot. The procedure tolerates methoxy, chloro, fluoro, cyano, trifluoromethyl, and carbomethoxy groups.

  已经开发了螯合辅助的钯催化的2-芳基吡啶和1-芳基吡唑CH键的级联溴化/氰化反应。值得注意的是，该反应使用K 3 [Fe（CN）6 ]作为安全且无毒的氰化物源，一锅即可提供中等至良好收率的芳族腈。该方法耐受甲氧基，氯，氟，氰基，三氟甲基和碳甲氧基基团。

  A Cp*Rh(III)/IL-based direct C-H bond cyanation system was developed for the first time. The system is a mild, efficient, and recyclable method for the synthesis of aryl nitriles. Many different directing groups can be used in this cyanation, and the reaction tolerates a variety of functional groups.
