Alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCO;H, such as metachloroperoxybenzoic acid (MCPBA). Peroxyacids transfer an oxygen atom to the alkene with syn stereochemistry, i.e. both C-O bonds form on the same face of the double bond, through a single step mechanism without intermediates. The oxygen atom farthest from the carbonyl group is the one transferred. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions H. CI CI HO
