The epoxidation of an alkene is the conversion of the #"C=C"# double bond to an oxirane.



An oxygen atom joins to each of the alkene carbons to form a three-membered ring.

The reaction is usually carried out in the presence of a peroxyacid.

An example is the reaction of but-1-ene with m-chloroperoxybenzoic acid (MCPBA) to form 1,2-epoxybutane.
