Web10 Feb 2024 · -O ketyl complex, 3 was treated with oxidants (CS 2, Se) and reducing agents (Mg 0, KH, or [SmI 2 (thf) 2]). Thus 3 was oxidised to tpc by Se. Treatment of 3 with KH led to a ligand exchange process giving an unusual diketyl species [Yb(DippForm)(tpc.-O) 2 (thf) 2] (10), which has two cisoid tpc.-O-ligands in very close proximity.
