Baeyer Villiger oxidation
The reaction of ketones [1] with peracids [2] produces esters [3] .
The oxygen of the peracid is inserted between the carbonyl carbon and the alpha carbon of the ketone. This reaction was described by Adolf von Baeyer and Victor Villiger in 1899. Read more...

Wittig reaction
The Wittig reaction uses phosphorus ylides [2] to transform aldehydes and ketones [1] into alkenes [3] . Triphenylphosphine oxide is obtained as a by-product [4].

Formation of Cyanohydrins
Cyanohydrins [3] are formed by the reaction of aldehydes or ketones [1] with hydrocyanic acid [2] and are compounds that contain a cynane and a hydroxy group on the same carbon.

2,4-Dinitrophenylhydrazine assay
This is a specific analytical assay for aldehydes and ketones. Carbonyls [1] react with 2,4-Dinitrophenylhydrazine [2] to form phenylhydrazones [3] which precipitate yellow.
The appearance of a precipitate is an indicator of the presence of carbonyls in the medium. Read more...
