Halogen Derivatives of 1,4-Dioxan

Methods for obtaining mono-, di-, and poly-chlorinated derivatives of 1,4-dioxan by the direct substitution of hydrogen atoms by chlorine are surveyed, together with synthetic reactions yielding fluoro-, chloro-, and bromo-dioxans. Methods of obtaining halogenoalkylated dioxans containing fluorine, chlorine, or iodine atoms are described. Consideration is given to reactions of halogenodioxans making possible their use in organic synthesis, in particular of solvents for polymers. A list of 110 references is included.
