Visible-light-promoted oxidative dehydrogenation of hydrazobenzenes and transfer hydrogenation of azobenzenes

Green Chemistry, 2019
Visible-light-promoted oxidative dehydrogenation of hydrazobenzenes and transfer hydrogenation of azobenzenes are realized using Eosin Y as the photo-catalyst.

Synthesis of (2 H )‐Indazoles from Azobenzenes Using Paraformaldehyde as a One‐Carbon Synthon

Advanced Synthesis and Catalysis, 2019
Rhodium(III)-catalyzed hydroxymethylation followed by intramolecular annulation of azobenzenes using paraformaldehyde as a valuable C1-feedstock is described.

Photodecomposition of azobenzenes

Journal of Chemical Technology and Biotechnology, 1980
AbstractUpon ultraviolet irradiation azobenzene and decafluoroazobenzene in cyclohexane and diethyl ether solutions decompose into phenylazo, phenylazomethylene and aniline radicals. The major products formed in cyclohexane solution are N‐cyclohexylaniline, N‐cyclohexylpentafluoroaniline, phenylazocyclohexane, pentafluorophenyl‐azocyclohexane, 1‐phenyl‐

Azobenzene as a photoswitchable mechanophore

Nature Chemistry, 2023
Azobenzene has been widely explored as a photoresponsive element in materials science. Although some studies have investigated the force-induced isomerization of azobenzene, the effect of force on the rupture of azobenzene has not been explored. Here we show that the light-induced structural change of azobenzene can also alter its rupture forces ...

Phenylation of azobenzene

Journal of the Chemical Society B: Physical Organic, 1970
The substituent effect of the phenylazo-group in homolytic phenylation has been measured with azobenzene as substrate and nitrobenzene as reference compound. Even after allowance for the large number of sites of substitution the phenylazo-group was shown to equal the nitro-group in its activating power.

Rh(III)-catalyzed [4 + 1]-annulation of azobenzenes with α- carbonyl sulfoxonium ylides toward 3-acyl-(2H)-indazoles

Tetrahedron Letters, 2018
A Rh(III)-catalyzed [4 + 1]-annulation of azobenzenes with α- carbonyl sulfoxonium ylides was developed to access 2H-indazoles in moderate to excellent yields with good functional group compatibilities.

Direct ortho-mercuration reactions of azobenzene and ortho-substituted azobenzenes

Journal of Organometallic Chemistry, 1976
Abstract The mercuration of azobenzene occurred exclusively in the ortho -position to yield 2-chloromercuriazobenzene and a mixture which on iodination gave 2,2'and 2,6-diiodoazobenzene. Ten other ortho -substituted azobenzenes were mercurated and mercuration was found to occur predominately in an ortho -position.
