Abstract

The photodecomposition of adamantylideneadamantane-1,2-dioxetane (1) in the presence of Ce3+ is discovered. Electron transfer plays a dominant role in the reaction mechanism. The photoirradiation of solutions of1 and CeCl3 within the absorption region of the latter leads to the decomposition of1 with the initial quantum yield φ=0.29±0.03. The reaction is caused by the dynamic extinction of the photoluminescence of*Ce3+ ions by dioxetane1. Adamantanone is the main product of the photocatalytic reaction. However, side products of the interaction of the intermediate 1,4-dioxyradical anion with the solvent are also formed.
