Typically, when thinking about ketone to alkene reactions, one thinks of the Wittig reaction. However, I don't see an appropriate form of that reaction here. This was posed as a question on my problem sheet and I suspect - after having given it some thought - that it's just a Hoffman/...
The analogous reaction of ketones is less well-understood and is thus rare in the chemical literature. Chapters 3 and 4 discuss new advances in the field as well as the design and execution of the first enantioselective intermolecular aldehyde-ketone cross-coupling. Mechanistic studies point to a...
Ozonolysis of cyclic alkenes results in linear chains. For example, this ozonolysis of 1-methylcyclohexene gives the aldehyde-ketone below: When dealing with these types of examples it can bevery helpfulto number your carbons and also to take your time with redrawing. My advice is todraw the ...
an alkene reacts with acetic anhydride to give methyl alkenyl ketone.I am not sure of how this proceeds, a search on google displays no links to any relevant matter, and I have not successfully found this reaction in any of the other books I possess. According to me, it should have ...
Our approach yields moderate to high success across various alkenes, displaying diverse functional groups (achieving up to 75 % yield) with notable efficiency and selectivity towards aldehyde/ketone products. Moreover, the heterogeneous COF film, immobilizing (Et4N)2[FeIII(Cl)bTAML], exhibits ...

What alkyl halides are needed to prepare the given ketone using the acetoacetic ester synthesis? What carbonyl compounds might you start with to prepare the following compounds by Grignard reaction? List all possibilities. a) 2-methyl-2propanal b) 1-ethylcyclohexanol c) 3-phenyl-3-pentan...
adding a prefix to indicate the location of the double bond in the molecule. The IUPAC name of the simplest alkene, H2C=CH2, is ethene, which is derived from ethane. Propene is related to propane. Two alkenes, 1-butene and 2-butene, are related to butane; these two compounds, which ...
Answer to: Using the Wittig reaction, propose a synthesis of the following alkene, beginning with toluene and ethanol as your carbon-containing...
In the case of oct-1-ene and t-oct-2-ene the composition of the ketone product mixture is very similar, although with t-oct-4-ene a significant increase in the proportion of the 4-one is observed. The major product in all cases however in the 2-one. The latter almost certainly ...
