“Clicked” Hydrazone Photoswitches

Journal of the American Chemical Society
The length of the linker connecting a photoswitch to a material significantly influences the latter's properties, with "zero-length" linkers being ideal for optimal photomodulation. The 1,2,3-triazole formed through the "click" reaction between an azide and an alkyne has been used as such a linking motif in various areas of research spanning from ...

Salicylaldehyde Benzoyl Hydrazone

Acta Crystallographica Section C Crystal Structure Communications, 1995
The crystallographic characterization of N-(2-hydroxybenzylideneamino)benzamide, C 14 H 12 N 2 O 2 , reveals quasi coplanarity of the whole molecular skeleton, localization of the double bonds in the central -C=N-N-C=O chain, which has an E configuration with respect to the double bond of the hydrazone bridge, and an amide trans,s-cis configuration ...

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.
