These can be synthesized by treatment of halohydrins with a base, which is an intramolecular SN2 substitution. Another common preparation technique involves the direct oxidation of alkenes with peroxycarboxylic acids, which is a concerted addition reaction with a mechanism very similar to that for the formation of a bromonium ion in bromine addition to alkenes. Polymer resins of this class are compound are used as adhesives and structural materials. For ten points, name
