Reaction development led to the preparation of new Zr 2-pyridonate complexes for this useful transformation. No nitrogen protecting groups are required for this reaction, which is capable of assembling quaternary chiral centers a to nitrogen. Preliminary mechanistic investigations suggest bridging metallaaziridine species are the catalytically active intermediates for this alpha-functionalization reaction, while monomeric imido complexes furnish azepane hydroamination products.}, keywords = {ALKENES, ALKYNES, BOND ACTIVATION, COMPLEXES, GENERATION, HYDROAMINOALKYLATION, INTERMOLECULAR HYDROAMINATION, NITROGEN, REACTIVITY, UNACTIVATED OLEFINS}, isbn = {0002-7863}, url = {://000264792200038}, author = {Bexrud, J.
