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.

Vergleichende Untersuchungen zur Arylaminierung von Benzofuroxan-Derivaten

The amination of benzofuroxan 2a and monosubstituted benzofuroxans 2b-e with alkali metal salts of formanilides 1 and sodium acetanilides 6 is described.Thus, the reaction of 2a with 6a-d gives the benzotriazole 1-oxides 3a-d.The benzofuroxans 2b and 2c react with sodium formanilides to give the isomeric mixtures 3f/3g and 3h/3i.Potassium 4-nitroformanilide reduces 2a furnishing benzofurazan 7.Nitrosubstituted benzofuroxans such as 2d and 2e undergo a carbocyclic amination leading to the benzofurazans 8 and 9.
