Question

Question: What product is formed from the $\left[5,5\right]$ sigmatropic rearrangement of the following unsaturated ether?

Short answer

Answer

Step-by-step solution

Step 1: [5,5]  sigmatropic shift

The $\left[5,5\right]$sigmatropic shift is associated with the intramolecular rearrangement of the group at the fifth position and the fifth position of the other group.

The new sigma bond is formed between the fifth positions of the groups.

Explanation

In the given conversion, the group at the fifth position rearranges itself. Therefore, it is a $\left[5,5\right]$ sigmatropic shift.

$\left[5,5\right]$sigmatropic shift.
