By using planarchiral [2.2]paracyclophane‐containing N,O‐chelating ligands for tantalum‐catalyzedhydroaminoalkylation, one of the most versatile catalytic systems for this reaction to date was obtained. Convenient Csp3−Csp3 bond formation of amines with terminal and internal alkenes was enabled by the same in situ synthesized catalytic system of [2.2]paracyclophane‐basedpyridonates and Ta(CH2TMS)3Cl2

The design and synthesis of a mixed 2-pyridonate-Ta(NMe2)3Cl complex for the direct C-H alkylation adjacent to nitrogen in unprotected secondary amines are reported. The hydroaminoalkylation of sterically demanding internal alkenes gives the direct, catalytic formation of C(sp(3))-C(sp(3)) bonds. Substrate scope investigations reveal key strategies for further catalyst development efforts in this 100%

earth-abundant and cost-efficient titanium catalyst generated in situ using commercially available Ti(NMe2)4 and a simple to synthesize urea proligand. This system demonstrates high TOFs for hydroaminoalkylation with unactivated substrates and features easy to use commercially available titanium amido precursors. Additionally, a high catalytic activity, scope of reactivity, and regioselectivity are all demonstrated
