Physicochemical Properties of 1,2-Diacylhydrazines Derived from Aliphatic Carboxylic Acids

Russian Journal of General Chemistry, 2002
The solubility and resistance to oxidation and hydrolysis of 1,2-diacylhydrazines derived from acetic, propionic, butyric, and valeric acids were studied in view of possible application of these compounds for concentrating nonferrous metals. The pK1 and pK2 values of the 1,2-diacylhydrazines were determined. The stability of conformers and the electron

Design, Synthesis, and Insecticidal Activity of Novel Isoxazoline Diacylhydrazine Compounds as GABA Receptor Inhibitors

Journal of Agricultural and Food Chemistry, 2023
A series of isoxazoline derivatives containing diacylhydrazine moieties were designed and synthesized as potential insecticides. Most of these derivatives exhibited good insecticidal activities against Plutella xylostella, and some compounds exhibited excellent insecticidal activities against Spodoptera frugiperda.

Anionic 3,4-diaza[3,3]sigmatropic rearrangements of N,N′-diacylhydrazines

Tetrahedron Letters, 1991
Abstract N,N′-Diacylhydrazines rearrange under basic conditions to afford 1,2-disubstituted succinamides. The rearrangement can be rationalized in terms of [3,3]sigmatropic shifts of biscarboxamide enolates.
