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

Abstract

Herein, we disclose the synthesis of metallacyclic Cp*Co^III 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.

Keywords: C−H activation; cobalt; homogeneous catalysis; structural elucidation; weak coordination.
