Two series of diaza derivatives were prepared by solvent-free condensation of benzoic acid and 4-substituted phenylhydrazines in order to obtain phenylhydrazides (HYD series) and, by oxidation of these compounds, the corresponding benzoyldiazenes (DIA series). Both sets were evaluated as inhibitors of soybean 15-lipoxygenase activity and antioxidant capability in the FRAP and CUPRAC assays. The most potent inhibitors of both series exhibited IC50 values in the low micromolar range. Kinetic studies showed that at least the more active compounds were competitive inhibitors. Docking results indicated that the most potent inhibitor interacts strongly with Ile-839 and iron in the active site.

Using N′-aryl acylhydrazines as aryl donors, a novel copper(ii)-catalyzed homo-coupling reaction of N′-aryl acylhydrazines has been developed for the synthesis of N′,N′-diaryl acylhydrazines. We also provided a complementary procedure for the preparation of unsymmetrical diaryl acylhydrazines via cross-coupling reaction. These protocols featured mild reaction conditions, wide functional group tolerance and highly regioselective products. Control experiments indicated that this kind of coupling reaction might undergo a transient acyl diazene intermediate. This journal is

An approach to pyrazoline-fused chlorins by dipolar [3 + 2]-cycloaddition of iminonitriles to Meso-Tetrakis(pentafluorophenyl)porphyrin: Synthesis of new PDT photosensitizers

Meso-Tetrakis(pentafluorophenyl)porphyrin reacts at higher temperature with unstable iminonitriles (RC≡N+-N--Ar), affording pyrazoline-fused chlorins, according to dipolar [3 + 2]-cycloaddition pathway. The respective iminonitriles were in situ generated from the corresponding functionalized α-halogenohydrazine derivatives by 1,3-elimination of HX in the presence of base (NEt3, DABCO). This method allows synthesis of very attractive moieties which may be of potential use as sensitizers in photodynamic therapy (PDT).

Wang, Xiaoxia,Yu, Hongping,Xu, Peifang,Zheng, Renwei
, p. 595 - 597 (2007/10/03)
Acylbenzotriazoles were found to react with substituted hydrazines and aqueous hydrazine under very mild conditions, thus affording a facile synthesis of three types of acylhydrazines in moderate to excellent yields.

The synthesis of acylhydrazines by using hydrazine hydrate as the reductant to hydrogenate acyldiazenes is reported. Twelve acylhydrazines have been synthesized from acyldiazenes in excellent yields under mild conditions. This method is rapid, convenient, and efficient.
Reduction of Ag(I) by 1-acyl-2-arylhydrazines: Mechanism of photographic infectious development
Bowman, W. Russell,Forshaw, J. Anthony,Hall, Kevin P.,Kitchin, Jonathan P.,Mott, Andrew W.
, p. 3961 - 3972 (2007/10/03)
The photographic process of 'infectious development' in which 1-acyl-2-arylhydrazines reduce Ag(I) has been studied using analogues. 1-Acyl-2-aryldiazenes, resulting from oxidation of 1-acyl-2-arylhydrazines, are hydrolysed to anions of aryldiazenes (ArN = NH), which undergo further oxidation with loss of nitrogen to yield aryl radicals. The aryl radicals cause 'feedback inhibition' which is prevented by the addition of benzhydrol.
REACTIVITY OF CYCLOPENTANONE ENAMINES TOWARDS ACYL ARYLDIAZENES
Benedetti, Fabio,Forchiassin, Mirella,Russo, Claudio,Risaliti, Amerigo
, p. 663 - 668 (2007/10/02)
Reactions of 1-aminocyclopentenes 1 with acyl aryldiazenes 2 give 1:1 enaminic adducts 3 and 4, or 1,3,4-oxadiazines 5.Isolation of these products was not always possible in the reactions of 1-(piperidin-1-yl)- and 1-(pyrrolidin-1-yl)-cyclopentene.Acidic hydrolysis gave 2-(N-acyl-N'-aryl)hydrazinocyclopentanones 6 or 2-arylaminocyclopentenones 8, depending upon the amino moiety and the cyclic or open chain nature of the adducts.
