PYRIDAZINES CONDENSED WITH A HETERO RING, IV FORMATION OF PYRAZINOPYRIDAZINE SKELETONS BY CYCLOCONDENSATION OF 4,5-DIAMINO- AND 3,4,5-TRI-AMINOPYRIDAZINONES

Koermendy, Karoly,Ruff, Ferenc

, p. 587 - 599 (2007/10/02)

The cyclocondensation of 4,5-diamino- (3a, b; 5a - c) and 3,4,5-triaminopyridazinones (7a - c; 10a - c) with α-dioxo compounds in Methyl Cellosolve solution, which is a slow process, is significantly speeded up in glacial acetic acid owing to proton catal
