Condensation of 2-hydrazino-3-phenylquinoxaline with representative ketones to yield ketone hydrazones was investigated. Pyrolysis of the hydrazones yields a 1-substituted s-triazolo[4, 3-a]quinoxaline with concurrent elimination of a hydrocarbon. Factors which apparently govern the elimination of alkyl groups from hydrazones are discussed. The kinetics of the Pyrolysis reaction have been studied and the mechanism for this type of cleavage was presented.
