The Trofimenko–Tebbe alliance: The sterically crowded, monoanionic scorpionate ligand TptBu,Me provides a unique environment for the isolation of discrete rare-earth metal complexes with Y[BOND](CH3){Al(CH3)4} and La[BOND](CH2) moieties (see structure; C gray, H white, Al orange, B red, La pink, N blue); the latter shows promising reactivity as a Tebbe reagent analogue.
