Organic Letters, Год журнала: 2023, Номер 25(35), С. 6501 - 6505

Опубликована: Авг. 28, 2023

A Bi(OTf)3-catalyzed oxidative cross-coupling reaction of 3-hydroxycarbazoles with arenols was developed under mild conditions. Both substrates were used in a 1:1 molar ratio the presence catalytic amount Bi(OTf)3. The carried out an oxygen atmosphere at 30 °C to afford C1-symmetric hydroxybiaryls good yields (up 94%) high chemo- and regioselectivity.
