= 0.17-0.26) and chemical (>90%) yields. The initial byproduct of the photoreaction, 2-naphthoquinone-3-methide, reacts rapidly with water (k(H2O) = 144 +/- 11 s(-1)) to produce parent 3-hydroxy-2-naphthalenemethanol. The o-quinone methide intermediate can be also trapped by other nucleophiles or converted into a photostable Diels-Alder adduct with ethyl vinyl ether.
