Synthesis of Cyclic (Alkyl)(amino)carbene-Stabilized Copper–Iron Heterobimetallic Complexes and Their Application in Pyridine Hydroboration

In this report, we synthesized heterobimetallic complexes supported by cyclic and bicyclic (alkyl)­(amino)­carbenes (CAAC and Et BICAAC) [( Me2 CAAC)­CuFe­(η5-C5H5)­(CO)2]­(1) and [( Et BICAAC)­CuFe­(η5-C5H5)­(CO)2] (2), respectively, featuring an iron–copper bond. Complex 1 demonstrates catalytic a...

Description
Summary:In this report, we synthesized heterobimetallic complexes supported by cyclic and bicyclic (alkyl)­(amino)­carbenes (CAAC and Et BICAAC) [( Me2 CAAC)­CuFe­(η5-C5H5)­(CO)2]­(1) and [( Et BICAAC)­CuFe­(η5-C5H5)­(CO)2] (2), respectively, featuring an iron–copper bond. Complex 1 demonstrates catalytic activity for selective 1,4-hydroboration reactions of pyridine derivatives. Detailed computational studies provide additional insights into the electronic structure of complexes 1 and 2 and elucidate the catalytic pathway.
