Web10.6.2 Hydroboration–Oxidation of Alkenes. Hydroboration-oxidation is another method for converting alkene to alcohol; however, in anti-Markovnikov regioselectivity, OH is bonded to the carbon with a greater number of hydrogens, and the hydrogen atom is bonded to the carbon with fewer hydrogens. Figure 10.6c Hydroboration-Oxidation of Alkenes WebThe addition of halogens to an alkyne proceeds in the same manner as halogen addition to alkenes.
