Start by converting phenylacetylene to 2-phenyl-3-butyn-2-ol using hydroboration-oxidation. This is a two-step process. a. Add 1,2-dibromoethane and borane-tetrahydrofuran complex to phenylacetylene to form the boron-alkyne complex. b. Oxidize the boron-alkyne complex with hydrogen peroxide to yield 2-phenyl-3-butyn-2-ol.
