Fewer C-H bonds Web1 day ago · A photocatalytic oxygen-isotopic labeling protocol has been developed, in which 18 O and 17 O-labelings of carbonyls in ketones and aldehydes were efficient and selective in a single step using oxygen-isotopic waters (H 2 18 O or H 2 17 O) as the sources of oxygen isotopes. This strategy was extended to the in-situ formed ketones from the …

WebAldehydes and ketones are simple compounds which contain a carbonyl group - a carbon-oxygen double bond. They are simple in the sense that they don't have other reactive groups like -OH or -Cl attached directly to the carbon atom in the carbonyl group - as you might find, for example, in carboxylic acids containing -COOH. Examples of aldehydes WebA comparison of the properties and reactivity of aldehydes and ketones with those of the alkenes is warranted, since both have a double bond functional group.
