, p. 666 - 671 (2007/10/02)
Azidopyridazines 3, 4, 24 and tetrazolopyridazines 10, 13, 28 can be converted to the corresponding aminopyridazines, by reaction with triphenylphosphine via phosphazenes and subsequent hydrolysis (Staudinger reaction).
Ring Closure of 4-Azido-3-phenyl-pyridazines to Pyridazinoindoles
Stadlbauer, W.,Pfaffenschlager, A.,Kappe, Th.
, p. 781 - 783 (2007/10/02)
The cyclization of 4-azido-3-phenylpyridazines and 7-azido-6-phenyltetrazolopyridazine by heating with strong acids like methanesulfonic acid affords 5H-pyridazinoindoles or 10H-tetrazolopyridazinoindoles, respectively, whe
