TL;DR: It is demonstrated that DNPH is not exclusively selective for carbonyl groups, because it also reacts with sulfenic acids, forming a DNPH adduct, through the acid-catalyzed formation of a thioaldehyde intermediate that is further converted to an aldehyde.

TL;DR: In this paper, the Schiff base ligands derived from hydrazone were synthesized and spectroscopically characterized by FT-IR, 1H NMR, UV-Vis spectroscopy, X-ray crystallography and cyclic voltammetry.

TL;DR: Claisen condensation of 4-acetamide pyrazolone 2 with diethyl oxalate have been utility to afford new 4-oxaloacetyl antipyrine 3, which upon hydrazinolysis of the ester function to obtain the acetohydrazide derivative 18 which used as starting material to synthesize 1,2,4-triazol 19 and hydrazone 20 derivatives.

TL;DR: The discovery of two new classes of catalysts for hydrazone and oxime formation in water at neutral pH, namely 2-aminophenols and 2-(aminomethyl)benzimidazoles, is reported.

TL;DR: The results of the correlations of these constants by Hammett and Yukawa-Tsuno equations exclude the presence of the hydroxyazo form 1B in equilibrium with 1A in agreement with the spectral data as mentioned in this paper.
