The 1,4-endoperoxide of 1,4-dimethoxy-9,10-diphenylanthracene (1) rearranges under mild acidic conditions to the 1,2-dioxetane 3, which has been characterized by NMR.The decomposition of 3 is catalyzed by fluorescers (such as 1) in a bimolecular process w

The photochemical cycloreversion of 1,4-Dimethyl-9,10-diphenylanthracene-1,4-endoperoxide (DDA-PO) is described in the wavelength range from 253 to 334 nm.The wavelength dependence of the photocycloreversion quantum yield Q1 indicates the existence of two different reaction channels, both starting from upper excited singlet states Sn (n >= 2).The reaction proceed adiabatically, however, not the parent hydrocarbon 1,4-Dimethoxy-9,10-diphenylanthracene (DDA) but only oxygen is produced in an electronically excited state.Upon irradiation with light of the wavelength 280 nm cycloreversion takes place with a large quantum yield of Q1=0.78.DDA and O2 (1Δg) are formed in equal amounts.The results confirm the theory of Kearns and Khan. - Keywords: Photolysis / Quantum yields / Endoperoxid
