An air‐stable, heterogeneous , and recyclable catalyst composed of palladium nanoparticles entrapped in aluminum hydroxide was applied to a highly selective α alkylation. A wide range of aliphatic and aromatic ketones and primary alcohols were coupled to prepare enones in an O 2 atmosphere and ketones in an argon atmosphere (see scheme).
