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...

CH3 CH3 1. Hg(OAC), H20 2. NaBH НО, І CH3 CH, Hoc H₃C/ Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic H adds to the sp carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the product alcohol. Because a carbocation intermediate is formed, rearrangements can occur prior to the addition of water. To avoid the possibility of rearrangement and still give a Markovnikov...

CH2 1. (CH2CH2hCuli 2. H30* CH3 The coniugate addition of an alkyl group to an ß-unsaturated ketone is one of the more useful 1,4 addition reactions, just as direct additiona more useful 1,2-addition reactions. Conjugate addition occurs via the use of a lithium dialkylcopper reagent, also called a Gilman reagent. The addition of the dialky copper anion to the B-carbon to give a copper-containing intermediate. Transfer of an alkyl group to carbon and release completes the reaction. Draw curved arrows...
