formation of an intense electronicabsorptionband at 476 nm, which is attributed to the 1,4-diphenylcyclohexane-1,4-diyl radicalcation. The absorption maximum (lambda(ob)) of this transient occurs at a longer wavelength than is expected for either the cumyl radical or the cumyl cation components. Substitution at the para positions of the phenyl groups in this radicalcation by CH(3)O, CH(3), F, Cl

processes are reported for their synthesis, methods that directly install a primary amine group into C(sp3)-H bonds remain unprecedented. Here, we report a set of new-to-nature enzymes that catalyzes the direct primary amination of C(sp3)-H bonds with excellent chemo-, regio-, and enantioselectivity, using a readily available hydroxylamine derivative as the nitrogen source. Directed evolution of genetically-encoded
