Preparation of masked 2,2-difluoro-1,3-diols and 2,2-difluoro-1,3,4-butanetriol via photochemical and thermal addition of oxygenated radicals to 2,2-difluorovinyl carbamate
T. Okano et al., Preparation of masked 2,2-difluoro-1,3-diols and 2,2-difluoro-1,3,4-butanetriol via photochemical and thermal addition of oxygenated radicals to 2,2-difluorovinyl carbamate, SYNLETT, (9), 2001, pp. 1449-1451
Photoreaction of difluorovinyl carbamate in some alcohols except for methan
ol 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 ini
tiated bynzoyl peroxide. Radical product of 2,2-Dimethyl-1,3-dioxolane was
converted into masked 2,2-difluoro-1,3-propanediol.
