The Prins reaction and cyclopropanation of the light fraction obtained by distillation of the technical grade divinylbenzene and consisting of a mixture of 1,3- and 1,4-divinylbenzenes with admixture of 3- and 4-ethylstyrenes were studied. These reactions quantitatively give the corresponding gem-dichlorocyclopropane and 1,3-dioxane benzene derivatives. The structures of the synthesized compounds were confirmed by NMR spectroscopy and mass spectrometry.
