Similar reaction … WitrynaStep 3: The acetate ion functions as a base deprotonating the oxonium ion to give the alcohol. This completes the oxymercuration part of the reaction. Step 4: ( mechanism not shown) The hydride reduces the Hg off, creating a C-H bond while breaking the C-Hg bond. This is the demercuration part of the process. This step is not stereoselective.
