A new type of sp3-like N-centered radical has been generated by selective energy transfer catalysis. Upon photoexcitation, homolytic N−O bond cleavage of N-indolyl carbonate in the presence of an Ir-complex produced N- and O-centered radicals. The high spin density at the C3 position of indole led to radical recombination with O-centered radical, affording valuable 3-oxyindole derivatives without decarboxylation. Transformations of desired products into various molecules were also demonstrated.
