Scope of the photocatalytic phenol cross-coupling. Conditions: 2.0 mol % MesAcr+BF4–, 25 mol % 4,4’-di-tert-butylbiphenyl, HFIP, air, blue LEDs, 35 °C, 48 h. Reported yields are of isolated material; yields in parentheses are based on recovered starting material. Values in brackets are isolated yields in the absence of the biphenyl. aReaction stopped at 24 h; bSolvent = ClCH2CH2Cl: HFIP (1:1); cortho-ortho product recovered in 9% yield.
