Description
Summary:A regioselective synthesis of unsymmetrical and symmetrical biphenols and binaphthols via oxidative coupling of phenols or naphthols in the presence of K 2 S 2 O 8 in CF 3 COOH under ambient conditions is described. Interestingly, the 1 : 1 ratio of H 2 O and CH 3 CN solvent mixtures at 80 °C instead of CF 3 COOH provided substituted unsymmetrical quinones. A gram-scale synthesis of biphenols and binaphthols was demonstrated. A regioselective synthesis of unsymmetrical and symmetrical biphenols and binaphthols via oxidative coupling of phenols or naphthols in the presence of K 2 S 2 O 8 in CF 3 COOH under ambient conditions is described.
