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).
Claims15
A process for making unsaturated .alpha.-amines from olefins wherein the .alpha.-amines have a base chain of carbon atoms having the same number of carbon atoms as the olefin, comprising:
- placing a liquid olefin having at least three carbons and an .alpha.-hydrogen;
- a catalyst having the general formula LL'MoO(X-Y) wherein L is selected from a group consisting of monoanionic ligands, and dianionic ligands, L' is a neutral oxygen, nitrogen, or sulfur neutral donor and X-Y is selected from a group consisting of, a peroxo ligand or a nitroso ligand;
- and an aminating agent having the general formula RNHZ wherein Z is selected from a group consisting of,
- a hydroxyl,
- an alkoxy,
- a halo, and
- a sulfonate ester, and
- wherein R is selected from a group consisting of,
- a hydrogen,
- an alkyl,
- an aryl,
- a carbonyl
- a carboalkoxy or
- a carboxamido,
- in a reaction vessel.
