Fig. 3: Scope of transition-metal-free APEX reactions.

a Reactions were carried out on a 0.20 mmol scale for cyclic aryliodonium salt 2. aConditions for reactions with benzene: 1a (2.0 equiv., used as an additive), 2 (1.0 equiv.), KOt-Bu (5.0 equiv.) in benzene (2 mL) at 110 °C under Ar for 3 h. b Access to an N-doped nanographene fragment. Isolated yields are reported.
