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

hydroaminoalkylation of terminal alkenes or styrenes enables a direct and 100 % atom-efficient synthesis of amines and can generally result in the formation of two regioisomers, the branched and the linear product. Herein, we report that high-yielding intermolecular hydroaminoalkylation reactions of styrenes can be achieved with excellent regioselectivities in the presence of the commercially available

reactivity of in situ generated tantalum complexes for the intermolecular hydroaminoalkylation of amines has been explored. Increased conversion was observed with the sodium salt of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBDNa) paired with the tantalum precursor Ta(CH2SiMe3)3Cl2 at 110 °C. Terminal alkenes underwent hydroaminoalkylation with a variety of secondary amine substrates to give substituted secondary
