Abstract
The facile production of acid sensitive aldehydes and ketones via photochemical intramolecular &hydrogen atom transfer in 1-alkoxy-and l-(benzyloxy)-9, 10-anthraquinones (1) was investigated. Irradiation of 1 in argon purged methanol generates the primary photoproducts, l-(RCH (OMe) O)-and l-(ArCH (OMe) O)-9, 1O-anthrahydroquinones (2), respectively. Upon exposure to air, the intermediate anthrahydroquinone is rapidly ...
