arylhydrazone
An arylhydrazone is an organic compound characterized by the functional group Ar-NH-N=CR2, where Ar represents an aryl group and R can be hydrogen or an alkyl or aryl group. It is formed by the condensation reaction between an arylhydrazine and a carbonyl compound, such as an aldehyde or ketone. This reaction typically involves the nucleophilic attack of the nitrogen atom of the arylhydrazine on the electrophilic carbon atom of the carbonyl group, followed by the elimination of a water molecule.
Arylhydrazones are important intermediates in organic synthesis. They are frequently employed in named reactions such as
