Towards Homoleptic Borylene Complexes: Incorporation of Two Borylene Ligands into a Mononuclear Iridium Species

摘要

The incorporation of subvalent Group 13 ligands into the coordination sphere of transition metals has always been a challenging task, particularly in the formation of homoleptic complexes. Although metastable or sterically protected subvalent E~1 (E = Al, Ga, In) precursors have become accessible during the last few decades, for example, E~1 halides, [{Cp*E})_nCp* = η~5-C5Me5), and [{EC(SiMe3)3)_n].
