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%

achieved by rapid C−H alkylation of unprotected secondary arylamines with unactivated alkenes. The combination of Ta(CH2SiMe3)3Cl2, and a ureate N,O‐chelating‐ligand salt gives catalytic systems prepared in situ that can realize high yields of β‐alkylated aniline derivatives from either terminal or internal alkene substrates. These new catalyst systems realize C−H alkylation in as little as one hour

Tantalizingly simple: The common organometallic starting material TaMe3Cl2 can be used for the catalytic CH functionalization reaction, hydroaminoalkylation. The substrate scope for this readily accessed compound includes unactivated terminal and internal alkenes, styrene derivatives, and both alkylaryl‐ and dialkyl secondary amines (see scheme).
