Evidence for the Existence of a Terminal Imidoscandium Compound: Intermolecular CH Activation and Complexation Reactions with the Transient ScNAr Species

Abstract

Don't blink or you'll miss it: A transient imidoscandium complex (see scheme) can be generated by several routes. The imido ligand can activate the CH bond in pyridine and benzene, and it can be complexed with Al(CH3)3 to yield an imide zwitterion. A combination of isotopic labeling, reactivity, and theoretical studies strongly endorse formation of a terminal imido ligand at scandium.
