Abstract
A process for making unsaturated .alpha.-amines from olefins wherein the process includes adding an aminating agent, an olefin and a molybdenum based catalyst to a reaction vessel having a nitrogen atmosphere. The catalyst may be described by the general formula LL'MoO.sub.2, L.sub.2 L'MoO.sub.2, or LL'MoO(X--Y).
