A regioselective and tunable synthesis of 1,5-disubstituted 1,2,3-triazloles from oxidative and eliminative [3+2] cycloadditions of nitroolefins and organic azides under solvent-free condition in the presence and absence of commercially available CuO nano

A new copper-catalyzed [3 + 2] cycloaddition/oxidation reaction of nitro-olefins with organic azides has been developed to afford 1,4(-NO2),5-trisubstituted 1,2,3-triazoles. This reaction sequence has a broad substrate scope and affords NO2-substituted 1,2,3-triazoles with high regioselectivities and in good to excellent yields. The involved oxidative process overcomes the elimination of HNO2 for general cycloaddition of nitro-olefins with organic azides, which shows a high atom economy and potential applications.

The reactions of alkynes and α-nitro-olefines with methylazide and phenylazide was studied.In contrast to known reactions with alkynes which are non-regioselective, methylazide and phenylazide react regiospecifically with α-nitro-olefines and give only one type of triazole after elimination of HNO2.These reactions are very useful synthetic approaches to 1,2,3 triazoles.

Phenylazide and methylazide reacts with title olefines and gives two isomeric triazoles without nitro group, and 4-nitro-1,2,3 triazole.The isomerisation of starting alkenes explains the formation of isomeric triazoles.Oxydation of amino-nitro-diazocompounds in equilibrium with 1,2,3 triazolines leads to 4-nitro-1,2,3 triazoles.
