Abstract The reaction of P (O)[BOND] H compounds with p-quinones could proceed through either 1, 4-or 1, 6-addition pathways by employing different additives to selectively give the corresponding C-and O-phosphoryl hydroquinone derivatives in good yields. Oxidative double 1, 4-addition of P (O)[BOND] H compounds to p-quinones was also achieved by tuning the solvent, affording a facile synthesis of bis-substituted hydroquinones with ...
