Article abstract of DOI:10.1016/S0040-4039(00)92114-2

The 1,3-dioxane formed by uv irradiation of o-isopropoxybenzophenone is produced by intramolecular cyclization of a hydroxy enol ether, the disproportionation product of the 1,5-biradical formed by triplet state hydrogen abstraction. The enol ether is stable in the absence of acid.
