Weakly Coordinated Cobaltacycles: Trapping Catalytically Competent Intermediates in Cp*CoIII Catalysis

다국어 초록 (Multilingual Abstract)

Herein, we disclose the synthesis of metallacyclic Cp*CoIII complexes containing 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.
Chasing unicorns: A versatile platform was developed for capturing thermodynamically unfavored cobaltacyclic species containing weakly chelating moieties (see picture). The strategy offers the opportunity to not only fully characterize direct analogues of key transient reactive species but also interrogate their reactivity and intermediacy in different Cp*Co‐catalyzed processes.
