General Description

(E)-bis(4-fluorophenyl)diazene, also known as bis(4-fluorophenyl)diazene or (E)-1,1'-di(4-fluorophenyl)diazene, is a chemical compound containing two 4-fluorophenyl groups connected by a diazene (-N=N-) linkage. It is a diazene derivative and has potential applications in organic synthesis and coordination chemistry. Diazene compounds have been studied for their potential use in organic light-emitting diodes (OLEDs) and as photoswitches. The (E)-bis(4-fluorophenyl)diazene compound has not been extensively studied, but its properties and potential applications make it an interesting subject for further research in the field of organic chemistry.

The improved method of oxidation of 4-fluoroaniline to 4- fluoroazobenzene

The improved method of oxidation of 4-fluoroaniline to 4- fluoroazobenzene with K3Fe(CN)6/KOH and 2,4,6-tri-tert-butylphenol as catalyst is described for the first time in this paper. This report offers an efficient and rapid method to prepare azobenzene and a possible mechanism is also suggested.

Rhodium(III)-catalyzed regioselective C–H nitrosation/annulation of unsymmetrical azobenzenes to synthesize benzotriazole N-oxides via a RhIII/RhIII redox-neutral pathway

A Rh(III)-catalyzed regioselective C–H nitrosation/annulation reaction of unsymmetrical azobenzenes with [NO][BF4] has been developed to achieve high-yielding syntheses of benzotriazole N-oxides with excellent functional group tolerance. Computational studies have revealed that this oxidative C–H functionalization reaction involves an interesting redox-neutral Rh(III)/Rh(III) pathway without the change of Rh oxidation state.

Bifunctional Cs?Au/Co3O4 (Basic and Redox)-Catalyzed Oxidative Synthesis of Aromatic Azo Compounds from Anilines

An eco-friendly alkali-promoted (Cs?Au/Co3O4) catalyst, with redox and basic properties for the oxidative dehydrogenative coupling of anilines to symmetrical and unsymmetrical aromatic azo compounds, was developed. We realized a base additive- and molecular O2 oxidant-free process (using air), with reasonable reusability of the catalyst achieved under milder reaction conditions. Notably, the enhanced catalytic activity was also linked to the increased basic site concentration, low reduction temperatures, and the effect of lattice oxygen on the nanomaterials. The increased basic strength of the cation-promoted catalyst improved the electron density of the active Au species, resulting in higher yields of the desired aromatic azo compounds.
