Concept explainers
Interpretation:
Using acetylene and any necessary organic and inorganic reagents, an efficient synthesis for the given
Concept Introduction:
>Alkylation of acetylene takes place in two steps. Acetylene has two acidic protons, which can be abstracted by a strong base.
>In the first step, the acetylene is treated with sodium amide to convert the acetylene to its conjugate base.
>The acetylide ion reacts with an
This sequence converts acetylene to its monosubstituted derivative, which is also a terminal alkyne.
>Repeating this sequence of steps using a different alkyl halide converts the acetylene to its disubstituted derivative. The triple bond is internal in this derivative.
