Amide hydrazones from hydrazones and sulphonyl chloride–amide complexes

J. Chem. Soc. C, 1967
Hydrazones of 5-nitro-2-furaldehyde, 3,5-dibromosalicylaldehyde, and o-hydroxyacetophenone condense with the carbonyl group of NN-disubstituted aliphatic amides in the presence of sulphonyl chlorides to yield amide hydrazones.

Hexafluoroacetone hydrazone chemistry

Journal of Fluorine Chemistry, 1972
Abstract Hexafluoroacetone hydrazone condenses with ketones and aldehydes to give azines. β-Diketones give either azino-enols or hydrazino-ketones depending on the substrate. Aldehydes capable of aldol condensation and some α, β-unsaturated carbonyl compounds give pyrazoles.

Ueber die Hydrazone

Berichte der deutschen chemischen Gesellschaft, 1888
Die Verbindungen der Hydrazine mit den Aldehyden und Ketonen sind in neuerer Zeit so haufig Gegenstand des Versuchs und der Discussion gewesen, dass es zweckmassig scheint, dafur einen besonderen Klassennamen einzufuhren. Die Nomenclatur der Hydrazine habe ich so viel mir moglich derjenigen der Amine nachgebildet.
