The scope of the reaction was tested with the synthesis of a small library of indole derivatives by irradiating the precursors 15a-15u in the presence of the iridium catalyst 16 with 15 W blue LED light (λ = 465 nm). The details of the photoreactor used for derivative synthesis are described by Li et al. In total, 16 so far unknown F-tagged derivatives were synthesized successfully with yields ranging from 52% to 80%, showing the compatibility of this transformation with differently substituted precursors (Scheme 4).
