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%
