Table 2. Scope of the C8–H Arylation of Quinoline N-Oxides with Iodoarenes under Thermal (T) and Microwave (MW) Conditions^a.

^aThe reactions were carried out with 0.5–1 mmol of the substrate for 16 h (T) or 50 min (MW). The yields are reported for isolated 8-arylquinoline N-oxides. The C8/C2 ratios are reported in brackets for the crude product before chromatographic purification.

^b5.5 equiv H₂O was used.
