Synthesis of Pyridazine Derivatives. XXIII. Synthesis of Isomeric Azolopyrido (3,2-d) - and Azolopyrido (2,3-d) pyridazines
The synthesis of six new parent azolopyridopyridazines (I-VI)
is described. Electropnilic substitutions were studied on two isomeric
imidazopyrd.dopyridazines and it was found that position 3 is
attacked
Syntheses in the Pyridazine Series. XXXII. Some Investigations on Polynuclear Systems Containing a Pyridazine Ring
Some 5,6-dihydrobenzo[f]phthalazines have been aromatized
to II and the structures of a number of nitro derivatives prepared
from several polynuclear systems (III, IV, V) , have been established
