Abstract

The photochemistry of a quinone methide (Ia) was investigated. Ia was unchanged on photolysis of an alcoholic solution (0.0064 M) with a high-pressure mercury lamp (Pyrex filter). However irradiation of a highly dilute solution of Ia or a sensitized reaction (acetophenone) gave an alcohol adduct (IIe in methanol and IIf in isopropyl alcohol) which might be formed via triplet excited state(s) of Ia. The methanol adduct IIe was also formed by the irradiation of Ia in methanol with a low-pressure mercury lamp through quartz. In this case the formation of He appears to be initiated by photochemical decomposition of methanol.
