МСРВА 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 - XT...

REVIEW Topics [References) CH HC OCH Br2 CH3 B H3C CH,OH H₂C CH₂ Electrophilic addition of hypohalous acids to alkenes yields a 1,2-haloalcohol called a halohydrin. Halohydrin formation, however, does not result from the addition of HOBr, for example. Instead the addition is done indirectly by reaction of the alkene with Br, in the presence of water. The reaction also works with Cl2 to give chlorohydrins instead of bromohydrins. The reaction proceeds through a cyclic intermediate known as...
