Question

Identify the reagents you would use to accomplish the following transformation:

\ce{CH \equiv CH} \rightarrow \ce{CH2=CH-CH2-CH3}

The transformation above can be performed with some reagent or combination of the reagents below. Give the necessary reagent(s) in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer.

A. 1) O₃; 2) DMS
B. 1) R₂BH; 2) H₂O₂, NaOH
C. MeI
D. H₂, Lindlar's cat.
E. Na, NH₃ (l)
F. NaNH₂
G. CH₃CH₂Br
H. H₂SO₄, H₂O, HgSO₄
I. MeONa

Jennifer Rojas · Answer

To accomplish the transformation of $\ce{CH \equiv CH}$ to $\ce{CH2=CH-CH2-CH3}$ , you can first reduce the alkyne to a trans-alkene and then perform hydroboration followed by oxidation. Here are the necessary steps:

Use Na, $\ce{NH_3 (l)}$ (which is option E) to convert the alkyne to a trans-alkene.
Use $\ce{R_2BH}$ followed by $\ce{H_2O_2}$ , NaOH (which is option B) to perform hydroboration-oxidation and obtain the desired product.

So, the string of letters indicating the correct order of reagents is "EB".
