Abstract

The formation of N,N-dimethylaminomethylenehydrazino derivatives
of pyridazine and azolopyridaz~nes is described and th.e
synthetic utility of these compounds is explored. An unusual transformation
could be observed with a aminomethyleinehydrazino
derivative where upon .nitrosation the side chain is trainsformed
into an azido group. From the corresponding N,N-dimethylaminomethyleneamino
derivatives two new tricyclic azolotriazolopyridazmes
could be prepared.
