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 CH bond in pyridine and benzene, and it can be complexed with Al(CH 3 ) 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.
