Activation of carbon dioxide by new mixed sandwich uranium(<scp>iii</scp>) complexes incorporating cyclooctatetraenyl and pyrrolide, phospholide, or arsolide ligands

Abstract

Mixed-sandwich complexes of the type [U(COT^TIPS2)(Cp^EMe4)] (where E is N or P and COT^TIPS2 = C₈H₆{1,4-SiⁱPr₃}) both reduce and insert CO₂ to afford dimeric, oxo-bridged, uranium carbamate and phosphacarbonate complexes.
