Together, these species undergo single-electron transfer to generate a transient and persistent radical pair capable of cleaving unactivated C–H bonds to furnish aminoxylated products. By tuning the structure of the donor, it is possible to control regioselectivity and tailor reactivity towards tertiary, secondary or primary C–H bonds. Mechanistic studies lend strong support for the formation and involvement of radical pairs in the target reaction.
