A P(NMe2)3-mediated annulation reaction of N-Acyldiazenes with isothiocyanates, producing 2-imino-1,3,4-Thiadiazoles, is reported. This reaction proceeds well with crude N-Acyldiazenes derived from the oxidation of hydrazides by iodi

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.

An efficient and convenient method for the synthesis of acyl-diazenes from acylhydrazines using NaNO2-acetic anhydride as a novel oxidant agent is reported. The reaction gives excellent yields and the reaction time is not long.
Oxidation of Ketone and Aldehyde Hydrazones, Oximes, and Semicarbazones and of Hydroxylamines and Hydrazo-compounds, using Benzeneselenic Anhydride

Benzeneseleninic anhydride (1; BSA) is an effective reagent for the mild regeneration of the carbonyl group from ketone phenylhydrazones, p-nitrophenylhydrazones, tosylhydrazones, oximes, and semicarbazones at 40-50 deg C.Tosylhydrazones and oximes of aldehydes are also readily converted into the parent aldehyde.The phenylhydrazone and p-nitrophenylhydrazone derivatives of aldehydes afford ketoazo-compounds.The ketoazo-species could also be prepared by oxidation of the corresponding hydrazide with compound (1).Both aromatic and aliphatic hydrazo-compounds and hydroxylamines can be oxidised to azo- and nitrozo-derivatives respectively.
