Use the curved arrow formalism to draw the complete mechanism for the aldol addition reaction. (It is not necessary to show the aldol condensation step). The reaction is: butyraldehyde with ether solvent and KOH to form the product 2-ethyl-3-hydroxyhexanal
Your aldol condensation procedure calls for refluxing vanillin in acetone and NaOH for an hour. Whatmight happen if you didn’t heat the reaction, or heated it for too short a time? a) A mixture of aldol products and hydroxyketone intermediates would form.b) No reaction would occur, as the heat is needed to deprotonate the acetone.c) The reaction would still be successful.d) No reaction would occur, as the heat is needed to dissolve the NaOH.
This reaction shows that an aldol-type reaction can be performed with a deprotonated imine as the nucleophile. On hydrolysis, the product is the normal B-hydroxycarbonyl compound.
