Draw a mechanism for a green aldol synthesis without solvent. using 3,4-dimethoxybenzaldehyde, 1-indanone, NaOH, HCl, ethanol and water
Homework Answers
Above is the mechanism of aldol synthesis since the product is an aldol.
There is a probability of elimination of water molecule through acid catalysis as here HCl is used. Then the product will be aldol condensation product. The mechanism is given below-

Aldol Condensation (multi-part question) 1. a. Why does mixing of solid 3,4-dimethoxybenzaldehyde and solid 1-indanone result a liquid solution? b. Why is the condensation (dehydrated) product rather than the aldol addition (hydrated) product obtained in this experiment? (What makes the condensation product exceptionally stable?) c. Why does the enolate ion of an aromatic ketone react faster with an aldehyde group (producing a crossed-aldol reaction) than with the carbonyl group of another molecule of ketone?

Why is the benzaldehyde preferentially attacked by the 1-indanone over another 1-indanone? Using a mortar and pestle, grind approximately 5 g of sodium hydroxide into fine particles. Add 0.50 g of 3,4-dimethoxybenzaldehyde and 0.40 g of 1-indanone to a test tube. Using a vortex mixer, gently mix the two solids together, forming an oil. Add 0.10 g of finely ground sodium hydroxide from Step 1 to the oil. Allow the reaction to sit for 15 minutes. Add 4 mL of...

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...
