	abstract = {<p>Using a tantalum ureate pre-catalyst, photocatalytic hydroaminoalkylation of unactivated alkenes with unprotected amines at room temperature is demonstrated. The combination of Ta(CH2SiMe3)3Cl2 and a ureate ligand with a saturated cyclic backbone resulted in this unique reactivity. Preliminary investigations of the reaction mechanism suggest that both the thermal and photocatalytic hydroaminoalkylation reactions begin with N\&ndash;H bond activation and subsequent metallaaziridine formation. However, a select tantalum ureate complex, through ligand to metal charge transfer (LMCT), results in photocatalyzed homolytic metal\&ndash;carbon bond cleavage and subsequent addition to unactivated alkene to afford the desired carbon\&ndash;carbon bond formation. Origins of ligand effects on promoting homolytic metal\&ndash;carbon bond cleavage are explored computationally to support enhanced ligand design efforts.</p>},
