Photoreaction of difluorovinyl carbamate in some alcohols except for methanol gave radical addition products as masked forms of 2,2-difluoro-1,3-diols. 1,3-Dioxolane also gave a radical product in thermal radical reaction initiated bynzoyl peroxide. Radical product of 2,2-Dimethyl-1,3-dioxolane was converted into masked 2,2-difluoro-1,3-propanediol.
