Alkenes can be converted to aldehydes or ketone via ozonolysis which is an oxidative cleavage reaction converting the C=C bond to a C=O bond. Whether an aldehyde or a ketone is obtained depends on the structure of the alkene.

Jan 23, 2023 · Alkenes can be cleaved using ozone (O 3) to form aldehydes and/or ketones. This is an example of a Ozonolysis reaction.

The Prins reaction is an organic reaction consisting of an electrophilic addition of an aldehyde or ketone to an alkene or alkyne followed by capture of a nucleophile or elimination of an H + ion. [1][2][3] The outcome of the reaction depends on reaction conditions.

Jan 23, 2023 · The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide (often called a Wittig reagent) to give an alkene and triphenylphosphine oxide.

Apr 23, 2013 · Ozonolysis with O3 converts alkenes into carbonyl compounds. Reductive workup with Zn or CH32S gives aldehydes. Oxidative workup converts aldehydes to COOH

The Wittig Reaction allows the preparation of an alkene by the reaction of an aldehyde or ketone with the ylide generated from a phosphonium salt. The geometry of the resulting alkene depends on the reactivity of the ylide.

The Wittig reaction or Wittig olefination is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide called a Wittig reagent. Wittig reactions are most commonly used to convert aldehydes and ketones to alkenes.

In the presence of PdCl 2 (MeCN) 2, 1,4-benzoquinone, and t-BuOH, aryl-substituted olefins can selectively be oxidized to aldehydes. In this efficient and aldehyde-selective Wacker oxidation, very good yield of aldehyde can be obtained, and up to 99% selectivity can be achieved with styrene-related substrates.

A catalytic amount of a composite material, RuO 2 /BaTi 4 O 9, in combination with NaIO 4 in EtOAc-H 2 O has been shown to efficiently cleave alkenes, affording ketones, aldehydes and/or carboxylic acids in high yields.
