A novel synthesis of diversely substituted 2,2′-biphenols through Pd(ii)-catalyzed, tBuOOH-oxidized, and hydroxyl-directed C(sp2)-H hydroxylation of [1,1′-biphenyl]-2-ols has been developed. Notably, this finding is distinct from previous reports in which [1,1′-biphenyl]-2-ols underwent an intramolecular C-H activation and C-O bond formation to afford dibenzofurans under the promotion of Pd(ii) but in the absence of tBuOOH.
