1-naphthol deriva- tives for photochemical reactions requiring excited-state naphtholate ions, such as quinone methide formation. Our re- sults show that three types of naphthoquinonemethides (26a, 26b, and 27) are readily photogenerated in aqueous solution by irradiation of 1-naphthols. Photolysis of the parent 1-naphthol (1) in neutral aqueous solution gave 1,5- naphthoquinonemethide 26a as well as the non-Kekule
