The ligand is key: Palladium(II)-catalyzed C−H carbonylation reactions of methylene C−H bonds in secondary aliphatic amines lead to the formation of trans-disubstituted β-lactams in excellent yields and selectivities. The generality of the C−H carbonylation process is aided by the action of xantphos-based ligands.
