1,2,3-Triazolium Ylide. — The reaction of 3-azido-2-chloropyrazine (I) with pyr-azoles or triazoles affords intermediate azidobisheteroaryl derivatives, which are con-verted into novel polynitrogen-fused tricycles by thermolysis. 3-Azido-2-chloropyri-dine (VIII) is less reactive and gives the 2-pyrazolylpyridine (IX) in low yield. — (NYFFENEGGER, C.; PASQUINET*, E.; SUZENET, F.; POULLAIN, D.; GUILLAUMET, G.; Synlett 2009, 8, 1318-1320; CEA Le Ripault, F-37260 Monts, Fr.; Eng.) — Mais
