説明

Attempts were made to examine the effect of substituents at 1-position of 6 (1H)-pyridazinone ring on ring-contraction reaction into pyrazole ring. It was concluded that methyl and non-substituted derivatives do not undergo ring-contraction, but para-substituted phenyl derivatives do regardless of the electronic character of substituents in the para position.
