Chapter 14, Problem 39PP

Interpretation Introduction

Interpretation: The reagents for the overall transformation of the reaction to be predicted.

Concept Introduction:

Useful reagents:

1. 1. $\text{mCPBA}$: An oxidizing agent that will convert an alkene into an epoxide.
2. 2. ${\text{NaNH}}_{\text{2}}$: Act as a strong base which abstract hydrogen from the acetylene.
3. 3. Lindlar’s catalyst ${\text{(H}}_{\text{2}}\text{,Pd/C)}$: The hydrogenation of triple bond into a $\text{Z-alkene}$ using Lindlar’s catalyst, a poisoned form of palladium on barium sulfate.
4. 4. Birch reduction ${\text{(Na,NH}}_{\text{2}})$: Birch reduction also works for alkynes too, and is a good way of reducing them, to (Trans) $\text{methyliodide}$ double bonds.

To Identify: The reagents for the transformation of the given reaction.
