WebNov 13, 2024 · An alternate method for the synthesis of dibenzalacetone is the Aldol condensation. In this reaction, an aldehyde is treated with a ketone in the presence of an acid catalyst, such as hydrochloric acid or sulfuric acid. The reaction proceeds via the formation of an enol, which then reacts with the aldehyde to form the dibenzalacetone … WebStep 1: Synthesis of Benzoin This reaction is a classic--the conversion of two molecules of an aldehyde to an alpha-hydroxy ketone. The reaction is known as a benzoin condensation ("condensation" because two molecules become condensed to one molecule). This reaction, which requires a catalyst, if often performed with cyanide ion.
