Photolysis and thermolysis of 3,3,6,6-tetraaryl-1,2-dioxanes were investigated. The photolysis of 3,3,6,6-tetra(p-methoxyphenyl)-1,2-dioxane afforded 1,4,4-tri(p-methoxyphenyl)-3-buten-1-one and p-methoxyphenol through a novel C-O bond cleaved 1,6-diradical intermediate, while the thermolysis mainly afforded the expected decomposition product 4,4'-dimethoxybenzophenone through an O-O bond cleaved 1,6-dioxy diradical intermediate.
