REACTIONS DES METHYLAZIDE ET PHENYLAZIDE AVEC QUELQUES ALCYNES ET OLEFINES α-NITREES. SYNTHESE REGIOSPECIFIQUE DES 1,2,3 TRIAZOLES

Piet, J. C.,Hetet, G. Le,Cailleux, P.,Benhaoua, H.,Carrie, R.

, p. 33 - 44 (2007/10/03)

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.
