Question

Give the name (common name or IUPAC name) of intermediate product (a) in the following reaction.

The image presents a chemical reaction sequence. 1. **Starting Material**: A brominated allylic compound is shown as the starting material on the left, with a benzene ring attached to a propenyl group (C=C-Br). 2. **Reactions**: - **Step (a)**: The first reaction involves the treatment of the starting material with \(Br_2\) followed by \(2NH_2^-\). This suggests a substitution or an elimination process that possibly forms an intermediate or a product involving deprotonation or rearrangement. - **Step (b)**: The subsequent steps include treatment with \(NH_2^-\), followed by \(CH_3Br\), and finally hydrogenation using \(H_2\) in the presence of Palladium (Pd) as a catalyst. This sequence indicates functional group transformations involving nucleophilic substitution and reduction. 3. **End Products**: The final product after the series of reactions is not explicitly shown, but the progression of the reagents indicates a transformation involving the original allylic bromide structure into a possibly reduced and altered compound. This reaction sequence offers insight into organic reaction mechanisms and the stepwise transformation of molecular structures using nucleophilic and catalytic reagents.
