What does it really take to stabilize complexes of late transition metals with terminal oxo ligands?
Surprisingly stable: Noble-metal complexes with terminal oxo ligands are frequently postulated as intermediates, but they are generally considered elusive, as their d electrons destabilize the M=O units. Until recently, the isolation of such compounds was thought to require strong acceptor ligands, but now a remarkably stable Pt=O complex has been obtained employing a simple pincer ligand.
