摘要：
Mono- and diaryl-substituted 1,4-quinones were synthesized by the In(OTf)(3)-catalyzed conjugate addition of aromatic C-nucleophiles to 1,4-quinone derivatives followed by in situ dehydrogenation in water. Water was found to be beneficial to the reaction. The regioselectivity of the addition reaction in water was also examined.
