문제 56
Unlike hydroboration–oxidation, the addition of H2O catalyzed by H3O+ is not stereospecific. Thinking carefully about the mechanism of the reaction, give two reasons why.
문제 57
The first step of oxymercuration–reduction is stereospecific, and yet this fact wasn't emphasized in that discussion. Show the stereospecificity of the first step for the following alkene and then explain why the stereospecificity becomes unimportant after the second step.
