Table 2. Substrate scope of the photoexcited ketone-catalyzed C–H imidation of arenes ^{a , b} .

^aReactions were carried out on a 0.1 mmol scale with 2 (1.0 equiv.) and arenes (10.0 equiv.) under light irradiation (1500 W m^–2).

^bIsolated yields of 3 are indicated.

^cCrude products contained two isomers in a ratio of a/b = 7 : 1.

^d2.0 equiv. of K₂CO₃ were used.

^ePerformed with 10 mol% of XI (TBS = tert-butyldimethylsilyl).
