does low heat favor the beta-hydroxy aldehyde compound in aldol condensations or the alpha-beta-unsaturated aldehyde?

low heat favors the beta-hydroxy aldehyde compound

does heat favor the beta-hydroxy aldehyde compound in aldol condensations or the alpha-beta-unsaturated aldehyde?

heat favors the alpha-beta-unsaturated aldehyde

What is the name of this aldol condensation product?

How do you improve selectivity of crossed aldol reactions?

use a very strong base (ex: LDA) or no alpha H's present

Is this aldol condensation kinetic or thermodynamic?

thermodynamic the proton transfer is reversible

Is this aldol condensation kinetic or thermodynamic?

kinetic proton transfer not reversible

where on this molecule does NaOH favor deprotonation?

where on this molecule does LDA favor deprotonation?

What type of rings is an intramoleular aldol reaction successful for? Why are other rings not favorable?

5 or 6 membered rings are successful other rings not successfull due to relative instability
