Herein, we disclose the synthesis of metallacyclic Cp*CoIII complexescontaining weakly chelating functional groups. We have employed these compounds not only as an exceptional platform for accessing some of the most widely invoked transient intermediates in C-H functionalization processes but also as competent catalysts in different Cp*Co-catalyzed transformations, including a benchmark coupling reaction

Described here is a synthetic approach to access two of the most widely invoked cationic cobaltacycles in Cp*CoIII‐catalyzed C−Hfunctionalization reactions by C−H activation. The unique stabilizing capability of MeCN was used to surmount the previously proposed reversible nature of the C−H metalation step. Moreover, it is revealed the boosting effect of 1,1,1,3,3,3‐hexafluoroisopropanol in the metalation
这里描述的是一种通过CH活化来访问Cp * Co III催化的CH功能化反应中最广泛调用的两个阳离子钴环的合成方法。MeCN独特的稳定能力用于克服先前提出的CH金属化步骤的可逆性。此外,揭示了在催化条件下,金属化步骤以及N-嘧啶基吲哚与二苯乙炔之间的反应中,1,1,1,3,3,3-六氟异丙醇具有促进作用。
