Studies on the Reaction Mechanisms in Heterocyclic Compounds. III. Chemical and Kinetic Studies on the Reaction of 2-Hydrazino-3-phenylquinoxaline with Carbonyl Compounds. (3)

Abstract

A red substance was obtained by the reaction of 2-hydrazino-3-phenylquinoxaline with excess aliphatic aldehyde. The structure of this substance was studied and the reaction rate was found to follow second-order kinetics. From these results, a mechanism was proposed and possible explanations for the red color were discussed.
