Homolytic addition of isopropyl alcohol to divinyl ethers of 1,1- and 1,2-diols

The reaction of divinyl ethers of 1,1- and 1,2-diols with isopropyl alcohol in the presence of tert-butyl peroxide gave, in addition to telomers, cyclic adducts (11), to which the 5-methyl-4-(2-hydroxy-2-methylpropyl)-1,3-dioxolane structure (in the case of divinyl ethers of gem-diols) or the 2-methyl-3-(2-hydroxy-2-methylpropyl)-1,4-dioxane structure (in the case of the vic-diols) was assigned.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 298–302, March, 1972.
