A general arene C–H functionalization strategy via ...

3 With optimized conditions for the photochemical coupling between 2 and 3 in hand, we implemented a one-pot sequence for the direct C–H alkylation of tert-butylbenzene 1 (Figure 2c). This was accomplished by addition of 1 to a mixture of dibenzothiophene (DBT) S-oxide and trifluoromethanesulfonic anhydride in CH 2Cl 2, forming 2 in situ.The crude mixture was treated …
