* Reduction of an epoxide  with lithium aluminium hydride or aluminium hydride  produces the corresponding alcohol. This reduction process results from the nucleophilic addition of hydride (H).
* Reductive cleavage of epoxides gives β-lithioalkoxides.
* Epoxides undergo ring expansion reactions, illustrated by the insertion of carbon dioxide to give cyclic carbonates.
* When treated with thiourea, epoxides convert to the episulfide, which are called thiiranes.
* An epoxide adjacent to an alcohol can undergo the Payne rearrangement in base.
