Jc. Piet et al., REACTION OF METHYLAZIDE AND PHENYLAZIDE W ITH SOME ALKYNES AND ALPHA-NITRO-ALKENES - REGIOSPECIFIC SYNTHESIS OF 1,2,3-TRIAZOLES, Bulletin des Societes chimiques belges, 105(1), 1996, pp. 33-44
The reactions of alkynes and a-nitro-olefines with methylazide and phe
nylazide was studied. In contrast to known reactions with alkynes whic
h are non-regioselective, methylazide and phenylazide react regiospeci
fically with cr-nitro-olefines and give only one type of triazole afte
r elimination of HNO2. These reactions are very useful synthetic appro
aches to 1,2,3 triazoles.
