Ring Transformation of Fused Pyridazines. IV. Reaction of Halo-substituted Fused Pyridazines with Ynamines
摘要:
Halo-substituted phthalazines reacted with two equivalents of ynamines to give penta-substituted pyridines through the N-N bond cleavage of pyridazine moiety. And it was proved that the N-N bond cleavage reaction of pyridazine ring is common to halo-substituted condensed pyridazines.
