Abstract
Succinaldehyde bis (diethyl acetal) and phenyl-, or ring substituted
phenyl-hydrazines cyclize in 250/o acetic acid into the
corresponding 1-N-aryl-dihydropyridazines I-IV. On the basis
of spectral and chemical evidence the structure of I-IV was
established, and the conditions leading to dihydropyridazine formation
were investigated.
