Koermendy, Karoly,Ruff, Ferenc
, p. 253 - 262 (2007/10/02)
The cleavage of the pyrazine ring by means of hydrazine hydrate was studied on various model compounds having the pyrazinopyridazine skeleton.The method developed makes possible the preparation of 4,5-diaminopyridazinediones (4a-c) from pyrazino2,
