Question

Propose a mechanism for the following reaction.

The image illustrates a chemical reaction involving two compounds with the presence of a catalyst. On the left side, there are two reactants: 1. The first reactant is 6-hydroxy-1-tetralone, which consists of a bicyclic structure with a ketone group (C=O) on one ring. 2. The second reactant is methyl vinyl ketone, which has a vinyl group (C=C) adjacent to a carbonyl group (C=O). An arrow indicates the reaction's direction, and above the arrow, it is labeled with "2 mol % NaOH," specifying that sodium hydroxide is used as a catalyst at a concentration of 2 mol percent. On the right side, the product is shown: - The product is a larger bicyclic compound showing the addition of the vinyl group from methyl vinyl ketone to the aromatic ring of the first reactant. This results in a new carbon-carbon bond and an extended conjugated system, forming a more complex ketone structure. This reaction is an example of an aldol condensation, facilitated by the basic environment provided by NaOH, which aids in the formation of the carbon-carbon bond.
