We were unable to transcribe this imageLab 8: Preparation of an a B-Unsaturated Ketone via Michael and Aldol Condensation Reactions of an a, B-Unsaturated Ketone via Michael and Aldol Condensation Reactions Finally, the aldol intermediate is dehydrated to form the final product, 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. The a Bunsaturated ketone that is formed is very stable because of the conjugation of the double bond with both the carbonyl group and a phenyl group. CH2Et-O CH...
Rheosmin is a saturated ketone obtained from an
alpha,beta-unsaturated ketone (a crossed aldol condensation
product) which is capable of undergoing hydrogenation to yield a
saturated ketone (Rheosmin). Using this technique, identify the
reagents needed to prepare Rheosmin via crossed aldol reaction.
Rheosmin 4-(4-hydroxyphenyl)butan-2-one
The following Aldol Condensation produces a mixture of SIX -alpha, beta-unsaturated carbonyl products. DRAW the structure of all Six the alpha, beta-unsaturated products obtained.

reactions
The carbon next to the carbonyl (C=O) carbon is called the a
carbon and the carbon next to the a carbon is called the b carbon.
An a,b-unsaturated car- bonyl compound is a carbonyl compound
(aldehyde, ketone, ester, etc.) that has a multiple (double or
triple) bond between the a carbon and the b carbon.

Postlab Assignment for Minilab 34 “Preparation of Aldol Condensation Products” 1. Explain why benzaldehyde is expected to be the most reactive aldehyde among the three aldehydes used in this experiment. (used benzaldehyde, 4-methylbenzaldehyde, and 4-methoxybenzaldehyde) 2. What is the role of aqueous NaOH used in the experiment you carried out? 3. How would you change the procedures in this experiment if you wished to synthesize benzalacetophenone (C6H5CH=CHCOC6H5). Just indicate the two main organic starting materials. 4. Write a mechanism for...
5) Draw the Structure of ALL the alpha/beta unsaturated carbon obtained as the dehydration products from the following aldol cond ůco + nsaturated carbonyl products that would be he following aldol condensation: NaOEt 6) The Aldol Condensation below provides only ONE PRODUCT. Provide the structure of the Aldol Dehydration Product and a Full Mechanism to account for its formation. C. –
1. Draw the reactants and dehydrated aldol product for your assigned aldehyde–ketone pair. 2. Using your assigned aldehyde–ketone pair, draw a base-catalyzed mechanism producing the dehydrated aldol product, an α,β-unsaturated ketone. Aldehyde is benzaldehyde Ketone is cyclohexanone
I need help determining if my isolated is beta hydroxyketone
or alpha-beta unsaturated ketone by the following IR. Also I have
to write the balanced chemical equation. We mixed Piperonal,
1-indanone, and Sodium hydroxide and produced our product via an
Aldol reaction.
Thanks for the help!

In today's experiment you will synthesize the a,ß-unsaturated ketone from 3- nitrobenzaldehyde and acetophenone via an aldol condensation. Once the aldol product forms, the reaction spontaneously dehydrates to the conjugated enone. This reaction fulfills some of the principles of green chemistry in that it has high atom economy, produces water as the only major byproduct, and uses ethanol as a non-toxic solvent. ON NaOH Etон Ph Which aldehyde will work better in this reaction as an electrophile: 4-cyanobenzaldehyde or 4-methoxybenzaldehyde?...
